Web Hosting, Domain Name System, DNS Protocol, DNS Resolver, Web Hosting Reviews

DNS is the abbreviation of Domain Name System which is a stratified naming system for services, computer and for any other possessions attached to the network or internet. DNS (Domain Name System) is responsible to links a variety of information with domain names allocated to each of the participants. The main task of DNS (Domain Name System) is the translation human language into the binary code. It is also serve as the distributed database that offers mapping among Internet Protocol addresses and host names. DNS makes facilitate the client to consign a domain name to groups of internet users in a significant way.

The DNS (Domain Name System) share out the conscientiousness of conveying domain names and mapping those names to IP addresses by delegating trustworthy name servers for each domain. Authorized name servers are consign to be accountable for their exacting domains, and then allocate other reliable name servers for their sub-domains. This method has through the DNS (Domain Name System) circulated and error understanding and has helped keep away from the need for a single central register to be constantly asked and updated. Usually domain name system restores different types of data such as mail server list that recognize email for a specified internet domain. In short DNS (Domain Name System) is a compulsory part of the functionality of the internet.

DNS Protocol


The DNS protocols contain various kinds of DNS messages that are progressions according to the data in their message fields. DNS protocols consist of message type which consists of queries; updates, and responses, DNS (Domain Name System) query message format has fixed length which is 12 bytes. DNS Header has fixed length and all other such as Question Entries, Answer Resource Records, authority Resource Records, Additional Resource Records have variable length. There are many other type of DNS (Domain Name System) messages or protocol such as DNS query message header, DNS query question entries, DNS resource records, Name query message, Name query response, Reverse name query message, DNS update message format, DNS (Domain Name System) update message flags, Dynamic update response message.

DNS resolvers


The DNS (Domain Name System) client side is called DNS resolver which is responsible for starting and sequencing the inquiries that eventually guide to a complete resolution of the sources required. DNS resolvers and DNS server are performing recursively on behalf of the resolver.

Resolving typically involve iterating through numerous name servers to locate the desirable information. Some resolvers purpose simplistically and can converse only with a particular name server and these all called stub resolvers which are rely on a recursive name server to execute the work of finding information for them.

DNS related files


DNS (Domain Name System) consist of boot which is a BIND boot configuration file, Cache.dns use for uploading, Root.dns which is a root zone file, and zone_name.dns which is a used when any zone entered and configured for a server.

DNS Resource Records


DNS Resource Records contains alphabetic list such as A which is a Host address (A) resource record, AAAA which is a IPv6 host address (AAAA) resource record, AFSDB which is a Andrew File System Database (AFSDB) resource record, ATMA which is a Asynchronous Transfer Mode address (ATMA) resource record, CNAME which is a Canonical name (CNAME) resource record, HINFO which is Host information (HINFO) resource record, ISDN which is a Integrated Services Digital Network (ISDN) resource record, KEY which is a Public key resource record, MINFO which is a Mailbox mail list information (MINFO) resource record, MX which is a Mail exchanger (MX) resource record, NS which is a Used to map a DNS (Domain Name System) domain name, etc.

DNS Architecture


The DNS Architecture consist of the following

Domain name space


Domain name space included a hierarchy of domain names and every node has zero or many source record having information linked with the domain name. The domain name space tree divided into zones starting at the root zone. A DNS zone contains of a compilation of linked nodes convincingly served by authorized name server because a single zone can host multiple server at a time.

Domain name formulation


Domain name formulation contains one or many parts which is technically called labels that are usually concatenated, and surrounded by dots. The right label express the peak level domain and it move down from right to left .every label to the left side classify a subdivision of the domain to the right. Each label has 63 characters and not surpasses a total length of 253 characters. Technically contains character signify as octet. The ASCII characters are allowed and included A to Z and 0 to 9, and hyphen. It is called LDH rule. The domain name relate as a minimum one IP address.

Internationalized domain names


The allowable character set of the DNS prohibited the demonstration of names and words of a lot of languages in their inhabitant alphabets or scripts. The IDNA system has approved by ICANN which diagram Unicode strings into compelling DNS character set. ICANN accepted the installation of IDN country code domain.

Name servers


The DNS system is upholder by a dispersed database system. This system employs the client server model and the knobs of database are the name servers. Every domain has minimum one authorized DNS server which distributed information about domain and name server of every domain subsidiary to it.

Authoritative name server


It is a name server which is responsible to answer about the configuration that it is held by an original source. Only Authoritative name server returned answer to inquiries related to domain name that have been exclusively configured by the administrator. Authoritative name server can be whichever slave master which uses an automatic method of the DNS protocol in contact in the company of its master server which maintains alike copy of the master account. Each zone of DNS ought to be a set of authoritative name servers. After the registration of domain name their setting up has need of the assignment of a primary name server and minimum one secondary server. The necessity of manifold name servers intends to make the domain still practical yet if one name server happen to unreachable or untreatable. The title of a primary name server is exclusively resolute by the precedence specified to the domain name registrar. For this reason usually only the completely competent domain name of the name server is compulsory.

Recursive and caching name server


The authorized name servers are enough for the process of the Internet. While with the authoritative name servers working Each DNS inquiry should start with recursive inquiries fro the root zone and every user have to employ resolved software competent of recursive operation. The effectiveness can be improved by dropping DNS traffic across the internet and boost performance in end user. DNS cache servers also supported by Domain name system which has ability to store information for a long period resolute in the configuration and these caching DNS server also called DNS caches. The amalgamation of DNS caching and recursive functions in a name server is not obligatory. These all can be put into practice separately in servers for particular reasons. All ISP commonly offer caching and recursive name servers for their client.

DNS and Active Directory


The active directory of windows server uses DNS as its domain manager location system. For any type of task such as updating, authentication, searching etc any computer based on window server use DNS to allocate domain controller of active directory and all these domain controller use DNS to trace each other.

DNS and WINS

The previous means of name declaration for a Windows network was WINS. DNS is unlike than WINS because WINS is flat and DNS is hierarchical name space. Those clients and application rely on NetBIOS prolong to use WINS for name declaration. WE can get maximum competence by the mixture both WINS and DNS for a variety of network resources and services.

DNS and DHCP


For DNS server of Widows the DHCP service offers default carry to register and update information for inheritance DHCP clients in DNS sector. DHCP integration facilitate a DHCP client that is incapable to dynamically update DNS sources records straightforwardly to have this information updated in DNS onward and undo lookup zones by the DHCP server.

Parked Domain, Addon Domain, Subdomains, Web Hosting, Compare Hosting

What is the difference between parked, addon, and subdomains?


Customers who are new to the hosting industry, at times, get confused between the control panel – parked, addon, and subdomains.

Here is a brief explanation of what it is all about so that you know what you should be going for, to match your requirements.

1. Subdomain


As the name suggests, it does not have a new domain name. It is a is a second website, with its own unique content, but will always carry the name of the parent/main domain.

As an example, you have the domain domain1.com. Its document root will be /home/username/public_html (this could vary at times). Contents will be loaded from this location when domain1 is accessed in the browser.

You decide to have a wordpress installation in a sub directory blog (/home/username/public_html/blog), which you intend to access as blog.domain1.com

This is when you go for a subdomain. The same contents can be accessed as domain1.com/blog or blog.domain1.com

If you own domain1.com, you can have many subdomains (depending on the plan you are on) as blog.domain1.com, help.domain1.com, gallery.domain1.com

2. An addon domain is a second website, with its own unique content. This type does require you to register the new domain name before you can host it.

You host domain1.com and would also want to host domain2.com too. You then need to register domain2.com and add it as an addon domain under the hosting account of domain1.com.

The document root would normally be /home/username/public_html/domain2.com (in this case),

The addon domain will look completely independent to the outside world with no means for anyone to know that this is running on an account under another site.

There are 3 ways of accessing an addon domain:

a. domain2.com

b. domain1.com/domain2.com

c. domain2.domain1.com

3. Parked Domain


A parked domain is NOT a unique website. This is a mechanism where you would want more than one domain name to point to the same website.

You have a main domain domain1.com to which you want to point domain2.com, domain3.com and domain4.com

All you need to do is add domain2.com, domain3.com and domain4.com as parked domains of domain1.com. Anyone accessing any of these sites will be greeted with the contents of domain1.com

Parked domains, again, would require you to register the domain names in order to use them.

It seems as if everyone has their own definition of cloud and hosted services. In truth, cloud and hosted are very similar — both are off-premise and are accessed through an Internet connection. While some believe that these services are essentially the same, experts argue that cloud services are more interrelated with other web-based offerings. When it comes down to it, the main difference between the two services is multi-tenancy.

Multi-tenancy


Multi-tenancy implements the sharing of resources and costs among a large pool of users and allows infrastructure to be concentrated in locations with lower costs, maximizing peak-load capacity and improving utilization and efficiency in systems that are often only used up to 10 to 20% of the time. Hosted services generally do not offer the same cost efficiencies, elasticity, or reliability as cloud services. As a result, cloud computing is more fitting for disaster recovery and business continuity.

The benefits for the cloud provider are amplified by only having to support a single version of software, the uniformity of its hardware environment, and its efficiency. The general rule is that if a solution is not multi-tenant, then it isn’t a cloud solution, and won’t have the same benefits.

Hosted Services


Hosted services are technology services offered by a provider hosting physical servers that are removed from the customer’s premise. A hosted service provider owns and oversees infrastructure, software, and administrative tasks at a private location. The system is available to clients, typically through a direct network connection that uses the Internet (VPN, Remote Desktop, etc.). There are three main elements of this service: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). These three combined encompass software, network capacity, and the equipment used to support operations such as storage, hardware, servers, and networking components.

Cloud Services


Cloud services are a subset of hosted services. Hosted services, even those accessible using the Internet, cannot be referred to as real cloud solutions unless they have been built to capitalize on the collaboration and interconnectivity that is a fundamental part of the cloud. Cloud applications are web-enabled, meaning, instead of being based on physical hardware, they are based in a shared virtual environment managed by a cloud-hosting provider. Only server installation and a device with an Internet connection are needed. Many line-of-business (LOB) applications are adding this functionality to their offering. Cloud servers can be constructed to provide varying levels of performance, security, and control to configure to your business’s needs.

Cloud servers allow your business to optimize IT performance without the overwhelming costs associated with the purchase and management of fully dedicated infrastructure. These servers are the ideal fit for businesses of variable demands and workloads. Cloud services offer on-demand utilities, multi-tenancy features with seamless uninterrupted scaling, and features that are sure to meet your business’ needs to adapt and help you meet the demands of your client base.

Free Website Hosting, Web Hosting Reviews, Web Hosting Guides, Compare Web Hosting
As the name suggests, free website hosting is a free non-paid web hosting service. There are many web hosts who provide subdomains to anyone who want to make website. Some of such popular free web hosts include Blogger and Wordpress. When you make your websites with these free website hosting services, your website gets such name as yoursite.blogspot.com and yoursite.wordpress.com. If you want to get a website with a domain name that doesn’t include any external site’s name, you must buy domain and then get web hosting which is usually a paid service. However, there are many web hosting companies that provide free web hosting with some or the other products/services that you buy from them.

Benefits of Free Website Hosting


There is this single biggest advantage of free website hosting and that is- it comes free without any cost. Now if you are amazed at why these free web hosting companies let you make a website free of cost then you may rest assured that they do not make any loss in this business. When you make your free website with them, they use your websites to place advertisements, banners and other forms of advertising media to earn revenue. Sometimes, the revenue from advertisement is shared with the owner of the website and sometimes it’s not. For example, when you get free web hosting from blogger and if you use their AdSense service, you get a share in the revenue generated from the advertisements that they place on your websites. On the other hand, when you make a free website using wordpress, you do not have any control on the placement or revenue generated from your free hosted website. The situation is altogether different when you get website hosted through paid web hosting service. You have full control over your website and it’s your decision whether you want to place advertisements on your site or not and if yes then the whole of the revenue generated from the website advertisement banners come to you only. There are many other differences between free and paid web hosting services.

Differences between Free and Paid Web Hosting


Here are some major differences between free and paid website hosting services. It will give you a better understanding about what is free web hosting service and whether it’s worth to opt for such free hosting for websites?

Advertisements on your website are controlled by the web hosting company that provides you with the free web hosting. It can use pop-ups, banners or any other advertisement on your site on which you do not have control. If also you have partial control, you may only decide what size of banner would be displayed where on your site. You won’t have control over what advertisement you will show on the website. On the contrary, when you avail paid web hosting, you have full control over your website and no outsider can decide anything for it.

Customer support is missing for free website hosting. Something which comes free cannot be asked to come with value added services. If something goes wrong with your website, there’s no customer support for websites made with free hosting. On the other hand, paid web hosting services not only give technical support to the customers but they also provide them with help guides, tutorials etc.

Low bandwidth and lesser data transfer capacity makes free website hosting vulnerable to greater downtime whereas paid website hosting gives you optimum bandwidth and data transfer for maximum uptime. You also can’t upload more images or videos when using free web hosting service as you don’t get enough disk space.

However, you can have best from the both worlds if you are ready to pay a little amount for any service that a web hosting company offers. For example, we offer a good web hosting package which comes with free online website builder and you have to just pay nominal rates. You get web hosting free along with many other facilities and services like email ID and free Google Adwords credit that you may use to advertise your website. This offer is better than any free website hosting service as you get full control over your website at practically very low cost! So, why wait!

Modern-day businesses are beginning to realize the importance of agile hosting services. It has become evident that the quality of hosting will determine the success of several crucial parameters such as SEO, bounce rate reduction, customer retention, and to an extent even the sales numbers. Given the relevance of these factors in determining the success of any business, companies have begun to look for faster and better hosting services.

SSD VPS Hosting, HDD VPS Hosting, Hosting Reviews, Hosting Guides, Compare Hosting

Gone are the days when companies would rely solely on the options provided by their website developers. Today, companies research the best possible solutions and evaluate what may be ideal for them. While most organisations have already made the move from Shared to VPS Hosting, smart organizations are diving further to determine the benefits between SSD vs HDD VPS Hosting. Let us try to find out what is the difference between Solid-State Drive and Hard Disk Drive along with your best possible option.

Mechanism


Before we take a look at the difference between SSD and HDD, it is vital to understand the underlying working mechanism of both technologies. HDD is a decades-old technology based on the mechanism of vinyl records. The HDD drive stores data in patterns magnetically. It has a thin metal disk which rotates at 7200 RPM to record and read data. Each driver is equipped with sensors capable of reading the data and sending it back to the motherboard.

The problem, however, arises with the fact that the disk will approximately spin 3.8 billion times a year leading to wear & tear and eventually some mechanical failure. On the other hand, SDD does not contain any moving parts. It stores data on interconnected flash memory chips. It can be seen as an upsized and advanced version of the regular pen drives. SSD uses a NAND-based flash memory making it more secure even when the device is turned off.

Speed


The working mechanism plays a significant role in dictating the outcome of SSD vs HDD Speed tests. HDD is equipped with moving parts bringing lesser read speeds and write speed as compared to SSD. SSD with its NAND flash memory is capable of clocking substantially high read and write speeds. The rotational latency in HDD leads to lower speeds when compared to SSD.

It is obvious that hosting servers employing SSD will offer better speeds than service providers using HDD storage. A faster loading website will give a significant boost to your SEO and improve your Google ranking. Search engine algorithms give importance to the website loading time in determining the rankings. Google and other search engines rewards websites with faster loading times as it provides better customer experience.

A faster loading website also gives a better customer experience as they can navigate without any lag and waiting time. Also, with the attention span of viewers reducing with ever increasing internet speeds, you have a narrow window to attract a customer before they decide to switch to another website. Web hosting with SSD ensures that your customer is delighted to visit your site and use your product or services.

Data Security


Data security is another crucial parameter that can severely affect your organization. The hosting servers are operational 24*7 which is different from the production environment. Overloading of hardware with I/O requests can lead to the failure of the hard disk. Such a failure could cause your website to go offline and raise uncertainty over the recovery of your data. While most data centres do keep a backup of the data, but there is always a possibility that you may lose some due to unforeseen circumstances. It is worth noting that the cost of data recovery with HDD is higher than that for SSD.

SSD comes with faster processing time reducing the risk of failure due to increased I/O requests. These also do not have any mechanical parts that could undergo wear & tear over a period of time and lead to mechanical failure. So, your data is extremely secure with SSD VPS hosting.

Environmental Factors


The usage of SSD drives in data centres results in lower power consumption when compared with the power consumed by the HDD drives. This is because the latter generates heat due to the mechanical moving parts and needs more energy to cool down. SSD drive, on the contrary, does not generate any such heat during its operation. Besides saving the environment, opting for SSD VPS hosting will also save your financial resources as the plans are comparatively cheaper.

With cloud computing well into the mainstream and steadily replacing roles currently filled by traditional server architecture, it’s time to ask the big question: can cloud hosting replace traditional file servers for storing and sharing files between employees in your organization? Serving, sharing, and storing files was probably the very reason many small and midsize companies built out their intranet infrastructure in the first place, and may still be the only reason that many companies have a server in their office or are renting server space. And as the workforce became more mobile, these servers took on the additional duties of sharing your internal files with employees on the road or working from home, even though they may not have always been designed for those functions.

Cloud Hosting, File Servers, Web Hosting Reviews, Compare Hosting

Cloud hosting, on the other hand, was born from a networked world with sharing, collaboration, and mobility being key considerations from the very beginning. Despite only being a relatively recent technological innovation, cloud computing has leveraged these strengths to quickly start eating away at the share of file hosting and file sharing duties of traditional server setups. Still, many companies are still hesitant to trust their files and security entirely to a third party where they may share space and resources with other companies, or entrust their proprietary data to some nebulous “cloud”. So which is better for your needs? What are the pros and cons of legacy file sharing servers compared to the newcomer cloud storage?

Traditional File Servers: Pros And Cons


File servers have been the mainstays and workhorses of the business world practically since business networking has been a term. There are a significant number of pros to keeping your files on an internal (or externally managed) server that you control. The biggest pro is ownership. While you may not own a rented server, if you are on shared hosting for example, you still control all of the contents of the server without doubt, and a hosting company cannot simply pull the plug on you, erase your data, or otherwise compromise the integrity of your data. This is even more so if you actually host your own file server on–premises or in a colocation space.

Another advantage of maintaining your own file server is the ability to configure it as much as you want, within certain limits (depending on your server type–self–hosted, shared, or dedicated). This gives you options about how you want files served, how credentials will be assigned, where people will be able to access files from, etc. This gives you flexibility and allows you to set things up in a way that is unique and specialized for your organization.

The major downside of having a traditional file server for sharing is the inflexibility and difficulty in maintaining such a server. Whether you host the server on–premises, have a shared hosting account, or a dedicated or co–located server, it is difficult to scale up and down as demand rises and falls. In fact, it’s impossible to do so dynamically in real time. That means during slow periods, you may be paying for way more server than you need, while during especially busy periods you may find that you are running out of bandwidth, RAM, or storage space. On top of that, unless you use a managed server, you will also have to be responsible for your own security and maintenance.

Cloud Storage: Pros And Cons


Cloud storage has pros that are the exact opposite of traditional servers. In order to utilize public cloud servers for storage and file sharing, you will be giving up a large portion of control in exchange for smooth operations. Public cloud storage allows you to not have to worry about buying server space, maintaining security, provisioning file space, or any of the other tasks that owning a server usually entails. The cloud storage provider will be responsible for security, for determining how access is granted, and where people can access the server from. You also gain flexibility. Many cloud storage services allow you to ramp services up and down to keep up with real–time demand. In fact, some will even do the automatic provisioning for you.

Downsides of a cloud storage and sharing solution are the loss of control that such a solution entails. You also have to worry about the cloud storage provider becoming a victim of cybercrime attacks. While most cloud service providers are much more security savvy than most small business IT teams, they are also much more likely to be seen as targets by hackers and other malicious elements.

Ultimately, each solution to the problem of file sharing and storage has its own pros and cons. Which works best for your business largely depends on your needs and your capabilities: a file server for companies with an IT budget to spend but a need for privacy, extra security, or their own special server build, or cloud storage for companies that don’t mind giving up a large measure of control in exchange for costs savings in IT management and technology.

Shared Hosting, WordPress Hosting, Web Hosting Learning, Compare Hosting

When creating a website, one of the most important decisions you’ll make is what type of hosting
plan to purchase. If you use a platform like WordPress, you’ll need hosting in order for your website to be available online. What’s more, selecting the right option is vital.

Two of the most popular choices for first-time website owners are shared hosting and WordPress hosting. Shared hosting is a type of low-cost plan where you share space on a server with other sites. WordPress hosting (which can be shared or not) means that the server comes optimized with the specific platform in mind.

In this post, we’ll talk you through your main hosting options, and explain how to find a plan that suits your needs. Let’s get started!

An Introduction to Shared Hosting


Put simply, a web hosting plan is a service that enables you to rent space for your website on a server. This is what gets your site online, and enables people to visit it. There are many different types of hosting plans available, however, and each one differs in terms of price and potential benefits.

Read More: Shared Web Hosting

One of the most common options is a shared hosting plan, where a single server is split between multiple websites. This is in contrast to dedicated hosting, where a single site has a physical server all to itself. Shared hosting is a popular choice for new and smaller sites, largely due to its low cost (often $5 per month or less).

While price is the primary benefit, there are some potential downsides to this kind of hosting. You’ll have to share resources with other websites, for example, which means your performance can suffer if those sites get a lot of traffic. Security can also be a concern, although a quality provider will offer additional protections.

What’s more, a standard shared hosting plan is not your only option. You can also opt for something more specific to the platform you’re using.

The Differences Between Shared Hosting and WordPress Hosting


As the name suggests, WordPress hosting is web hosting that has been optimized for the needs of a WordPress website. It’s important to understand that this isn’t a type of plan in the same way that shared hosting is. WordPress hosting can be shared, dedicated, or something else entirely.

What matters is that WordPress hosting better meets the performance and security needs of sites built using the platform. You may also get access to platform-specific features such as pre-installed sites, automatic WordPress updates, and dedicated WordPress support.

The details of your plan will depend on the provider you choose, of course. In addition, many hosts also offer both managed and unmanaged WordPress hosting plans. Unmanaged plans leave site optimization and server management up to you. A managed plan is slightly more expensive, but provides you with a lot more help keeping your site running smoothly.

How to Decide Which Type of Plan Is Best for Your Site


Both traditional shared hosting and WordPress hosting are viable options, making it difficult at times to choose the right one. However, directly comparing the two can make the decision easier.

Especially when you’re first starting out, one of the main criteria to consider is cost. As previously mentioned, shared hosting is about as cheap as it gets. This makes it a perfect option for those setting up new websites and blogs.

However, you’ll find that shared, WordPress-specific hosting plans can be almost or just as affordable as more platform-agnostic options. For that reason, it’s well worth looking into a WordPress hosting plan for most sites. A WordPress plan will be carefully designed to address the needs of your specific site, which is a significant benefit.

If you have the budget for it, you may also want to look into managed WordPress hosting. While these plans are often pricier, you’ll have a more efficient and secure site that’s taken care of by platform experts. This is an especially strong option for those completely new to WordPress, as well as business owners who don’t have the time or expertise to handle performance and security concerns personally.

Ultimately, there’s no one ‘correct’ choice of hosting for every website. You’ll need to assess the individual needs of your business and site. However, most WordPress users will be better off with a plan that takes their specific needs into account, whether that’s a shared option or something more powerful.

DNS, for Domain Name Service, acts as a look-up table that allows the correct servers to be contacted when a user enters a URL into a Web browser. This somewhat transparent service also provides other features that are commonly used by webmasters to organize their data infrastructure.

Operational Overview


DNS runs on DNS servers. When a user enters a URL, such as www.google.com, into a Web browser the request is not directly sent to the Google servers. Instead, the request goes to a DNS server, which uses a look-up table to determine several pieces of information, most importantly the IP address of the website that is being requested. It then forwards this request to the proper servers and returns the information requested to the user's Web browser.

Domain Name System


The DNS server looks at three primary pieces of information, starting with the top level domain. The top-level domain is denoted by suffixes such as .com, .org, and .gov. Once the top-dlevel domain is established, the second-level domain is analyzed. For example, the URL www.google.com possesses a top-level domain of .com and the second-level domain name google. The second-level domain is usually referred to simply as a domain name. Finally, the DNS server resolves the third-level domain, or subdomain, which is the "www" portion of the URL.

Features of Subdomains


Aside from the "www" subdomain zone, other subdomains are also worth noting. For example, subdomains such as "pop" "irc" and "aliases" exist. Each subdomain represents a different service that may be accessed on the server. For example, "pop" is used for email communications. The use of the DNS server to resolve the IP addresses of these different services allows for complex network architectures to be implemented. Despite being under the same domain name, these different services may be hosted on different machines or different geographical locations. This also allows a level of redundancy when using aliases, in case the primary domain server goes down.

User Benefits


DNS servers allow standard Internet users to use Internet resources without having to remember port numbers and IP addresses. Even similar services, such as different areas of the website, may be hosted at different IP addresses for security reasons. This allows users to memorize simple URL addresses as opposed to complex, nonintuitive lists of IP addresses and port numbers. This also allows private servers made by home users to be freely available yet somewhat shielded from having their IP address publicly known.

What is Primary DNS?


A primary DNS server is the first point of contact for a browser, application or device that needs to translate a human-readable hostname into an IP address. The primary DNS server contains a DNS record that has the correct IP address for the hostname. If the primary DNS server is unavailable, the device contacts a secondary DNS server, containing a recent copy of the same DNS records.

How Does a Primary DNS Server Work?

When a computer or device needs to connect to another device on the Internet, it typically uses a human-readable domain name, like “www.example.com”. The browser or application needs to translate the domain name into a numeric Internet Protocol (IP) address like “192.100.100.1”. This translation is done by the Domain Name System (DNS).

The device first contacts the primary DNS server that hosts the controlling zone file. This file contains the authoritative DNS information for the domain or subdomain. “Authoritative” means it is the trusted source for information like the IP address of the domain, administrator contact information, and settings like Time to Live (how long this IP address should be saved in a local cache).

The primary DNS server server resolves the query by returning the IP address for the requested hostname. However, if the primary server is slow to respond, or is unavailable, the device is referred to one or more secondary DNS servers.

What is Secondary DNS (Slave DNS)?


Changes to DNS records—for example, changing the IP for a domain name—can only be done on a primary server, which can then update secondary DNS servers, also known as slaves. DNS servers can be primary for one DNS zone and secondary for another DNS zone.

Web Hosting Reviews, Compare Hosting, Web Hosting, Primary DNS, Secondary DNS
A secondary server holds a secondary DNS zone—a read-only copy of the zone file, which contains the DNS records. It receives an updated version of the copy in an operation called zone transfer. Secondary servers can pass a change request if they wish to update their local copy of the DNS records.

Secondary DNS servers are not mandatory—the DNS system can work even if only a primary server is available. But it is standard, and often required by domain registrars, to have at least one secondary server.

Benefits of having a secondary DNS server for a domain:


◈ Provides redundancy in case the primary DNS server goes down. If there is no secondary server, when the primary fails, the website will become unavailable at its human-readable domain name (although it will still be accessible by its IP).

◈ Distributes the load between primary and secondary servers. Some resolvers use the Smooth Round Trip Time (SRTT) algorithm to prefer the lowest latency name server from the available pool of servers (primary and one or more secondaries).

◈ Part of a secure DNS strategy— DNS servers are exposed to security threats, first and foremost Distributed Denial of Service attacks (DDoS). Setting up an an external DNS provider with DDoS protection as a secondary DNS, is a common way to deflect DDoS attacks.

DNS Zone, Primary DNS and Secondary DNS Configuration


In the preceding discussion we referred to DNS zones. A DNS zone is a distinct part of the domain name space, delegated to a specific legal entity which is responsible for managing it.

For example, a root domain such as “acme.com” is a DNS zone, which can be delegated to a company, Acme Corporation Inc. Acme Corporation then assumes responsibility for setting up a primary DNS server, called an Authoritative Name Server, which holds correct DNS records for that domain.

DNS zones exist at higher and lower levels of the DNS hierarchy. For example, the Top Level Domain “.com” is also a DNS zone, which has an Authoritative Name Server providing DNS records for all the domains in the “.com” namespace. A subdomain, such as “support.acme.com” is also a DNS zone, which can be managed by Acme Corporation, or delegated to another entity.

Primary and Secondary DNS Management in Modern DNS Infrastructure


The classic primary/secondary DNS architecture is no longer used by modern, managed DNS providers.

Today, most DNS providers offer customers several name server IPs to use. Behind each of these IPs are pools of DNS servers, with requests routed via anycast (a one-to-many transport protocol). This provides improved redundancy and high availability compared to the master/slave model.

However, even in advanced DNS deployments, secondary DNS can help you:

◈ Migrate to new DNS infrastructure, with dependencies on old DNS servers — organizations may have tools, code, or legacy systems which point to an old DNS server hosted in their organizations. There may be scripts automatically creating DNS records (for example, if you provision a new subdomain for each of your customers). In order to migrate to a modern, managed DNS provider, without breaking your dependencies, you can define the DNS provider as a secondary DNS server. This will keep all existing processes in sync, but in case of failure or slow response of in-house DNS servers, the high-performance, managed DNS server will respond.

◈ Avoid single points of failure — high traffic sites and mission-critical web applications cannot tolerate outages. Even if using a managed DNS provider, administrators might prefer to use two providers, to avoid any single point of failure. A simple way to do so is to configure one provider as primary DNS server and the other as secondary. This way, all management and creation of DNS records is done with one provider, and in case of failure or slow response, the secondary takes over.

◈ Setup redundant DNS with one managed service — Want2host intelligent managed DNS can setup a dedicated DNS deployment for your organization, which runs on a separate network and servers from its regular managed DNS service. This gives you redundancy between two separate DNS servers, but can work with only one provider. The dedicated deployment is not shared with any other organizations, so it isn’t exposed to attacks targeting other customers on the Want2host DNS service.

Many-a-times it so happens that you purchase a domain name but before you can set up your website some issue arises. It could be anything from wanting to postpone the launch of the website or a backend issue and so, you have to wait! Well in such a scenario what would you do? Do you neglect the domain name or wait till you can figure out what next! The best way is to wait and the simplest way to do this is by parking your domain.

Web Hosting, Hosting Learning, Web Hosting Reviews, Compare Web Hosting

Let us have a look at what does parked domain mean:

Domain Parking is a process wherein you as an owner of the domain name can retain the domain name (say, for example, mybusinessworld.com) without hosting a functional website on it. In simple words, you can reserve your domain for future use with a ‘work in progress’ or an ‘under construction’ page.

Having covered what is a parked domain the next logical question that comes to mind is, why to use domain parking. There are several reasons why domain name owners would like to park their domain, let us see some of them:

1. To reserve it for the future


Many times, it might happen that you like a domain name but, you don’t know much about how to set up a website or need some time to do so. However, once you sort the idea in your mind and decide to set up the website, you see the domain name is no longer available.To save yourself from this hassle, you can park your domain. This way the domain is yours and no one else can register it until it expires.

2. Website not yet set up


In the first scenario, you didn’t have an idea of what kind of a website you wished to set up. However, sometimes it may also be possible that you have both the domain name as well as the idea for the website and yet your website isn’t up. This can happen due to several reasons. Some of them being- you’re unable to decide on the web hosting provider or it can be delayed due to some technical/personal reasons. Parking your domain name at a time like this helps you keep the domain till the issue is resolved.

3. Wish to shut down your website


Till now we’ve seen situations wherein your domain name doesn’t point to a website. But what if you already have a website? There are times you may be running more than one website and wish to discontinue one. But instead of discontinuing the functioning of your website immediately, you wish to wait till your domain name expires. In this case, you can opt for parking your domain and earn income from it.

4. Additional earning


One of the strongest reasons to park your domain is that you can earn money from it. Generating income from a non-functional domain name is easy. You can post advertisements & if someone visits your page and clicks on the advertisement, you get paid. Your revenue is generated based on the traffic and follows the pay-per-click model. This is one of the simplest ways to earn money and the best is you don’t have to do much. You should though, take care of the kind of content that is being displayed on your page.

Now that you know why you would want to opt to park your domain name.

You can either check with your registrar, if they offer domain parking facility or if they don’t provide this, then you can go for Sedo. Sedo stands for “Search Engine for Domain Offers” it is a professional web address trading platform. Also, it being a free service provider it is easy to set up and earn money. Moreover, you can cancel parking your domain at any given point.

At the end, even though you may have had the question as to what does parked domain mean with it sounding like an alien concept it isn’t, it is easy to understand & implement. Nonetheless, it is recommended that you research well on which domain you wish to park and where.

WordPress Hosting is, in most cases the ideal hosting for WP websites. Not only does it provide great performance owing to the fact that it is configured to be highly compatible with WordPress, but it also provides a range of WordPress management features. This makes it very easy for website owners to manage and maintain the website without having to allocate additional resources to do the same. Although different hosting providers provide different features, we will talk about the benefits of WordPress Hosting.

WordPress Hosting, Web Hosting, Hosting Learning, Compare Hosting

◈ Highly compatible with WordPress

◈ Enhances the performance of WP websites.

◈ WordPress is pre-installed to provide a plug and play environment for developers.

◈ Automatic WordPress updates to keep you up to date all the time.

◈ Cloud-based hosting infrastructure that provides a high level of scalability.

◈ Automated backups using CodeGuard.

◈ Daily malware scanning and security with SiteLock.

◈ Pre-installed plugins that make your job easier

◈ Managed services that take-up WordPress maintenance.

To get a better understanding of the benefits of WP Hosting, let’s look at them individually in detail.

1. Performance:


Every software will have its own system requirements that determine how efficiently the software will function. With that in mind, even WordPress as a software has its ideal system requirements. WordPress Hosting ensures that the hardware, firmware, and software configuration is highly compatible so that it runs efficiently.

Having a system that is compatible ensures that you do not run into performance issues and system freezes. If the system does not function properly, the hosted website may crash, or temporarily be out of service which will have serious implications on the website’s authority and visitor’s experience.

2. WordPress is Pre-Installed:


Developers who take up WordPress projects regularly would love this feature. With WordPress pre-installed, you have no need to spend time downloading and installing the CMS on the server. You just purchase the plan and begin developing the website. This saves a lot of time and you never have to worry about compatibility issues.

3. Automatic WordPress Updates:


Another important benefit for WordPress Hosting is automatic WordPress updates. Every update that is released comes with a bunch of improvements and bug fixes. If your instance of WordPress hosting is not up-to-date, not only will you lose out on these essential improvements and bug fixes, but also become more susceptible to external security threats. The automatic update feature of WP Hosting ensures that you are covered on this front.At times, the website you are hosting is not compatible with newer versions of WordPress. Although this scenario is very rare, it still persists. In such cases, turning off automatic updates is just a switch flip away.

4. Cloud-Based Hosting:


One of the biggest benefits of WordPress Hosting plans is that the hosting is Cloud-Based. Which means the advantages of Cloud Hosting are cascaded to the WordPress Hosting. These advantages include scalability at the click of a button and a high level of reliability as there is no single point of failure. Moreover, we integrate

Varnish Cache within this Cloud-based environment that has the potential to increase your website’s speed by 1000%.

5. Great Security and Backup:


Our WordPress hosting packages provide the option to include premium website security and backup tools. One of them being CodeGuard, which automatically takes website backup periodically so that you have enough restore points in case of a disaster. The other tool that our WP Hosting contains is SiteLock. This software regularly monitors the website for malware and security threats and notifies you to take necessary action. SiteLock can also be configured in order to deal with security threats automatically in case of an encounter.

6. Pre-installed Jetpack Plugin:


Plugins form a very strong base for WordPress development. Any task or functionality that you can imagine can be made possible with plugins. Our WP Hosting plans integrate certain essential plugins such as Jetpack plugin. This plugin can be used for a variety of functions including provisioning of WordPress themes, lazy loading, marketing services such as analytics, automated social media and SEO tools, Payment gateway integrations and high-end security for your website.

7. Managed Services:


Another very useful advantage is the inclusion of managed services. What this means is that the WP Hosting team takes care of dealing with all your website maintenance tasks. Without managed services, you as the website owner are responsible for taking care of the WordPress maintenance which requires resources.Managed services include a barrage of activities like scalability of hosting resources such as CPU, RAM and storage space. As your website grows, you will need more hosting resources to handle the incoming traffic load.This can be easily done by the managed team without you having to worry about the specifics.

Another example of managed services is the optimization of the WP Database. The WP Database holds all the important information of your website such as pages, posts, form entries, cookies, plugin settings, theme settings etc. As your website grows, this database becomes bulky. Bulky WP databases are usually slow and need to be optimized so that they do not affect the overall speed of the website. The managed hosting team takes care of this on their own without you having to intervene.

DNS is a host name to IP address translation service. DNS is a distributed database implemented in a hierarchy of name servers. It is an application layer protocol for message exchange between clients and servers.

Requirement


Every host is identified by the IP address but remembering numbers is very difficult for the people and also the IP addresses are not static therefore a mapping is required to change the domain name to IP address. So DNS is used to convert the domain name of the websites to their numerical IP address.

Domain :


There are various kinds of DOMAIN :

1. Generic domain : .com(commercial) .edu(educational) .mil(military) .org(non profit organization) .net(similar to commercial) all these are generic domain.
2. Country domain .in (india) .us .uk
3. Inverse domain if we want to know what is the domain name of the website. Ip to domain name mapping.So DNS can provide both the mapping for example to find the ip addresses of geeksforgeeks.org then we have to type nslookup www.geeksforgeeks.org.

Organization of Domain


DNS (Domain Name Server), Web Hosting, Hosting Learning, Compare Hosting

It is Very difficult to find out the ip address associated to a website because there are millions of websites and with all those websites we should be able to generate the ip address immediately,
there should not be a lot of delay for that to happen organization of database is very important.

DNS record – Domain name, ip address what is the validity?? what is the time to live ?? and all the information related to that domain name. These records are stored in tree like structure.

Namespace – Set of possible names, flat or hierarchical . Naming system maintains a collection of bindings of names to values – given a name, a resolution mechanism returns the corresponding value 

Name server – It is an implementation of the resolution mechanism.. DNS (Domain Name System) = Name service in Internet – Zone is an administrative unit, domain is a subtree.

Name to Address Resolution


DNS (Domain Name Server), Web Hosting, Hosting Learning, Compare Hosting

The host request the DNS name server to resolve the domain name. And the name server returns the IP address corresponding to that domain name to the host so that the host can future connect to that IP address.

Hierarchy of Name Servers


Root name servers – It is contacted by name servers that can not resolve the name. It contacts authoritative name server if name mapping is not known. It then gets the mapping and return the IP address to the host.

Top level server – It is responsible for com, org, edu etc and all top level country domains like uk, fr, ca, in etc. They have info about authoritative domain servers and know names and IP addresses of each authoritative name server for the second level domains.

Authoritative name servers This is organization’s DNS server, providing authoritative hostName to IP mapping for organization servers. It can be maintained by organization or service provider. In order to reach cse.dtu.in we have to ask the root DNS server, then it will point out to the top level domain server and then to authoritative domain name server which actually contains the IP address. So the authoritative domain server will return the associative ip address.

Domain Name Server


DNS (Domain Name Server), Web Hosting, Hosting Learning, Compare Hosting

The client machine sends a request to the local name server, which , if root does not find the address in its database, sends a request to the root name server , which in turn, will route the query to an intermediate or authoritative name server. The root name server can also contain some hostName to IP address mappings . The intermediate name server always knows who the authoritative name server is. So finally the IP address is returned to the local name server which in turn returns the IP address to the host.

When to choose reseller hosting over addon domains


Reseller web hosting and shared web hosting plans often include cPanel for managing your websites & domains. When you have multiple domains, you must decide on whether reseller hosting or a shared web hosting plan is a better fit.

Reseller Web Hosting


◈ master dashboard to control multiple cPanel accounts
◈ ability to create multiple cPanel accounts
◈ each cPanel account has a separate login; username & password
◈ resources are allocated to each cPanel (memory, cpu, processes etc)

Shared Web Hosting


◈ single cPanel login
◈ uses “addon domains” (directories) for additional domains
◈ no separate login for websites
◈ resources are shared among all websites on the account

When do we recommend using a reseller web hosting plan?


If you have more than a few domains that you’d like to host, we recommend a reseller hosting plan to keep each domain isolated via their own cPanel account. The two biggest issues with addon domains are the use of resources such as memory, cpu & processes and then security concerns. Addon domains within cPanel are not inherently insecure, but since the directories reside under the same system user, there is no isolation between them. Unfortunately, this means if for example, a WordPress website becomes compromised, it can potentially spread to other addon domains.

Reseller Hosting, cPanel Addon Domains, Web Hosting, Compare Hosting

While the addon domains & security does pose a risk to other websites residing on the same hosting plan, we do not see a higher ratio of compromised websites simply due to the fact that addon domains are being used. As long as the website(s) being hosted on the addon domains (and parent cPanel account) are properly secured, we see no issues with using addon domains.

Are you a web agency or providing website hosting services to customers?


If you’re providing website hosting services to customers or are hosting a large number of websites (from a web agency for example), we most definitely recommend using a reseller hosting account over a shared account with addon domains. There’s a few reasons for this, the main three being security, resources & accessibility. Having each domain on its own cPanel means that there is also a separate login.

You certainly would not want to have addon domains in this case as you would have to provide the same username/password to each customer in order for them to access anything within cPanel (which we HIGHLY do not recommend). Additionally, keeping each customer isolated from one another will ensure that in the event one site becomes compromised, it does not affect another customer site.

Lastly, resources are assigned per cPanel account, so having each website on its own cPanel means the resources are not being shared by any other account/website except for what resides on that cPanel account.

With addon domains (on a single shared web hosting account), if your cPanel account has 1GB of RAM available to it and you have 10 domains/websites via addon domains, all 10 of those websites are going to have to share that 1GB of RAM. With busy websites, this means contention, each website will fight one another for resources.

When to use addon domains?


If you have a shared web hosting account and would like to simply add a few personal or hobby type sites, we most definitely recommend addon domains for this. The concept of addon domains from cPanel is good however, when the websites being hosted using addon domains are customer websites or are busy sites, we don’t recommend using addon domains. Addon domains are another option that can be used for staging sites also, but we recommend using subdomains for that.

Are your sites income based or monetized sites?


If your websites are generating any type of income, we recommend that you at least host them on separate accounts. This could be a reseller hosting plan OR separate shared hosting plans if you don’t plan to add more sites over time. Shared hosting accounts can always be moved into a reseller account down the road if you add more accounts.

The biggest reasons we recommend multiple shared hosting cPanel accounts or a reseller account when you have multiple sites that are monetized is both performance and security.

If one of your monetized sites becomes compromised (let’s say a WordPress exploit from a bad plugin) and it spreads to your other site (via an addon domain), there’s a possibility that the platform being used for monetizing the site could pull the site from their platform. In instances like this, we feel the risk is simply too high and increases the possibility that the issue could interfere with the income being generated.

Web Hosting, Hosting Reviews, Hosting Learning, Compare Web Hosting

Consider this: you’ve set up your website and you finally have customers. However, the wait is long, and the website is slow to load. By the time it loads, you’ve lost your opportunity to convert a visitor to a paying customer – leading to a loss of revenue. In a matter of seconds, they’ve moved on.

Why?

Studies have shown that nearly half of the customers expect page load times of about three seconds. By recognizing this problem early enough, you can take steps to prevent this from happening. How? By implementing the right caching solution for your website.

What is Web Cache?


Caching refers to the process of storing data, temporarily, in a computing environment – namely a cache. When customers look at your web page, those files are automatically stored on the hard disk, in a cache subdirectory on their browser. When they return to look at that page, the browser can access those files from the cache, rather than returning to the original server to fetch the data again.

Web Hosting, Hosting Reviews, Hosting Learning, Compare Web Hosting

Without caching: When a customer visits your website, the browser will send a request to your server for site data, like content, media, code etc. The data is then sent to the customer’s browser. Each piece of this data needs to be loaded individually before it can be displayed. There are always delays while the transfer is happening and a lot of additional factors that can slow the process down. For e.g., if the visitor is located far away from your server, it can adversely affect your loading time.

With caching: The data is stored in a location close to your customer – it goes to where your customer is, cutting down on loading time. For example, web browser stores data at your customer’s end once the page is loaded for the first time. This reduces the page load speed by a mile for a returning user.

The advantages are clear. What you need to do is choose a caching solution that suits your website. There are many methods of caching available. We’re going to discuss three: server caching, browser caching and caching plugins and how each could impact your website.

Server caching: 

If your website is busy, dynamic, content heavy and experiences high volumes of traffic, you may want to look into server caching. One of the best cache servers is Varnish. This is how it works – when your customer visits your site, a series of requests are sent to the server to enable the page to load. The server then looks for the files pertaining to the request, execute any code related to that request and then return the web page to the user. By installing caching mechanisms like Varnish, it essentially acts as a middleman, between the user and the server and look out for duplicate requests from before. The next time the customer visits your website, Varnish will respond by quickly sending a cached version of the result. This can increase the speed of your site exponentially. It also cuts down on how much processing power you need to respond to high volumes of traffic.

Browser caching: 

Whenever a browser loads a web page, it needs to download all the files to display the page properly – this includes HTML, CSS, images and JavaScript. If your website has a lot of files, you can face two issues – first, large files take longer to load (especially if your customers are using a slow internet connection). Secondly, each file makes a separate request to your server, which adds to the work your server needs to do. Browser caching will help by storing some of the files on your customer’s browser. The first time your customer visits your site, it may take time to load, but as they continue to interact with your website (either by refreshing, revisiting or even moving to another page on your site) files are being cached onto their browser. This cuts down on the data that your customer uses to load your site, and it saves bandwidth on your server.

Browser caching works by identifying elements of your website that can be saved offline. These elements are those that are not likely to be changed on a regular basis – like your logo for instance. To enable browser caching, you’ll need to edit your HTTP headers in order to set expiry times for certain files. If certain files are updated frequently, you can give them shorter expiry times.

Caching plugins: 

Currently, WordPress powers nearly 33 per cent of the web. If your website is one among this number, you can look at third-party caching plugins. These are simple and easy to install. The only catch is the sheer number of plugins available to you. However, some of these plugins are highly recommended, like W3 Total Cache, which offers caching via memory, disk or CDN (Content Delivery Network). It also removes unnecessary or redundant data on posts, pages, feeds, JavaScript and more. Thanks to this you can save on server bandwidth, which leads to increased server performance, reduced download time, and boosts conversion rates – all good news for you. You can also look at other popular plugins like WP Super Cache and WP- FFPC.

What are the benefits overall?


1. Reduced network burden: Between your content and your customer, data can be cached at several points. For example with server caching, web pages are stored and served to your customer efficiently. When it is closer to the customer, requests will not place a burden on the network between the customer and your website – just the cache.

2. Increased performance: When you choose caching as an option, it frees up resources on the original server to improve the overall performance.

3. Ranking: Site speed is one of the most important factors when it comes to your website’s ranking. Faster websites are favoured by search engines (and aided by great SEO setting and good quality content). The slower your website, the lower you drop in the rankings.

4. User Experience: You want your customers to have the best experience on your website. A faster website will help your customers browse better. What’s more, cached data saves on your user’s data (to a certain extent) due to the fact that static files are less of a load, as compared to dynamic requests.

At the end of the day, caching is an excellent solution to speed up your website. Our Cloud Hosting services make use of advanced caching mechanisms like Varnish to ensure that the server caching is taken care off. Choosing which caching solution suits your website will require careful consideration on your part – which parts need to be cached and which data on your website will change with time.

Today, many organisations and enterprises are moving into a more hybrid cloud environment. And why not? Hybrid clouds are agile – they adapt and change to the needs of the organisation. With their unique mix of private, on-premises clouds and public clouds, you can get the scalability, low cost and reliability of a public cloud, while you can get the security, control and customisation and flexibility of a private cloud- It is the best of both worlds. It is projected that by 2020, almost 90 per cent of organisations would have shifted to a hybrid cloud environment (source). However, due to this flexibility and these two worlds (private and public) the security of a hybrid cloud becomes a bit more challenging. In this article, we’re going to look at how to secure hybrid cloud.

What is Hybrid Cloud?


Simply put, a hybrid cloud is an environment that uses a mix of third-party public clouds and on-premises, private cloud – with orchestration between the two. When workloads move between these two platforms – the private and public clouds – you get greater flexibility and more data deployment options. This allows you to respond to computing changes and business needs with agility. Sounds good right?

Web Hosting Reviews, Top 10 Web Hosting, Hosting Learning, Compare Hosting

In order to establish this unique cloud computing environment, you need the availability of a public Infrastructure as a Service (IaaS) like AWS (Amazon Web Services) Google Cloud Platform or Microsoft Azure. Secondly, you need the construction of a private cloud (either through a cloud provider or on your own premises). The third component is a good Wide Area Network (WAN) connectivity between the public and private cloud. Finally, you need to make sure that your Hybrid Cloud is secure. This is where the matter of hybrid cloud security comes in – why is it important and what does it entail?

Hybrid Cloud Security


While you may have a firm grip on the data in your own private cloud, once you begin to venture into the public cloud space, things become more complex. As more enterprises move to a hybrid cloud environment, more data security concerns arise. These are the top concerns:

1. Cross-Cloud Policy Management:

While policies and procedures within the organisation’s private data centre are set, these policies might not transfer well when it comes to the public cloud. Therefore, the challenge is to create, configure and maintain a security policy that is uniform across the entire network. This includes firewall rules, user identification/ authentication and IPS signatures amongst other things.

2. Data Leaks:

A key issue for data security administrators is data visibility. When it comes to deciding where data should be stored, organisations must put in the time, care and a tremendous amount of thought. And even then, it’s easy to lose track of the data without ensuring proper data visibility.

3. Data compliance:

Before organisations can move data and applications to a service provider cloud, they must make sure they understand all regulatory compliance laws that apply to their data – whether that’s customer credit card data or data spread across multiple geographical locations. Ultimately, it’s the responsibility of the organisation to make sure data of any nature is well-protected. Cloud providers and Cloud web hosting service providers will tell organisations which compliance standards they adhere to. If more is required then the responsibility lies with the organisation to spell out those needs.

4. Scalability:

All security tools, procedures and practices need to be scaled for growth. If that hasn’t been done, companies can hit roadblocks because they neglected to build a security architecture that scales itself to the organisation’s infrastructure resources.

This brings us to the final question: How to secure Hybrid Cloud?


While hybrid cloud environments are more complex, there are multiple hybrid cloud security solutions and practices organisations can put in place, to keep it secure.

1. Isolate Critical Infrastructure: Organisations store incredibly sensitive data on the cloud. However, access to this data needs to be isolated and restricted to a few key personnel, or those who specifically require it.

2. Securing Endpoints: Using the cloud infrastructure does not remove the need for endpoint security. Often, threats and attacks start at the endpoint level. Accordingly, enterprises and organisations need to implement proper endpoint security by choosing comprehensive security solutions that offer application whitelisting and browser exploit protection.

3. Encrypting data: Data – in transit and at rest – needs to be encrypted as a security measure. Organisations must also protect data, while it’s being used and processed by a cloud application. This will ensure that the data is protected for its entire lifecycle. While encryption methods vary according to service providers, organisations can choose the encryption method they prefer and then look for hosting providers who offer the same.

4. Back up Data: It is essential that organisations backup their data – both physically and virtually – in case an attack or system failure leads to a loss of data (either temporary or permanent). Backing up data for your website and other applications will ensure that the data is accessible at all times.

5. Create a continuity and recovery plan: It’s vital that organisations create a backup plan to ensure that operations continue to run smoothly in a time of crisis (this could include power outages at data centres or disruption of services). A recovery plan could include image-based backups, which will create copies of computers or VMs, which can be used to recover or restore data.

6. Risk Assessment: One good practice for organisations to follow is to constantly update risk assessment and analysis practices. That way, organisations can review the cloud provider’s compliance status and security capabilities. It also allows organisations to look at their own internal development and orchestration tools. Organisations must also keep an eye on operation management, monitoring tools, security tools and controls – both internally and in the public cloud. Vigilance like this allows security teams to maintain clarity and confidence in the controls that are currently in place and will give them time to modify them if required.

7. Choose a Reliable Web Hosting Provider: When choosing a Cloud Hosting provider for your website, organisations must look at the security capabilities. The service provider should be aware that security is a key concern and they should provide adequate security measures to keep your data safe. Good Cloud Hosting providers use the storage systems to ensure unshakeable stability. This ensures that you don’t have to worry about the loss of data due to hardware failures.

Ultimately, every hybrid cloud security issue has a corresponding solution. The trick is to identify specific problems early and then create a comprehensive security solution. If organisations do that, they will end up with a powerful hybrid cloud that functions smoothly, is easy to manage and remains secure.
