Web Hosting, Compare Web Hosting, Web Hosting Reviews, Web Hosting Guides

There is a bit of a buzz surrounding cloud web hosting these days and if you are researching various hosting options, you will certainly run across this term. But, there are only a handful of web hosts currently offering this solution, thus although it is a rather popular option it is also fairly new so your choices in web host are a tad limited.

As this solution gains in popularity, though, it is likely more and more hosts will start offering this as an option. This will benefit the customer by giving them more choices in companies to utilize, but it will also reduce the price for it with the increased competition in the market.

What is Cloud Web Hosting?


Cloud webhosting is hosting that uses the resources of several clustered servers. Basically, this means that your website uses the virtual resources of several servers to accommodate all the aspects of hosting your site. The load is balanced, security is taken care of and hardware resources are available virtually so they can be used when needed. The cluster of servers is the cloud.

Who can Benefit From Cloud Web Hosting?


Cloud hosting is often a solution for web sites that have outgrown the resources of their existing shared hosting provider. If a web site is extremely popular and causes a strain on the resources supplied by a shared server, you may need to find another solution. Often this solution is dedicated hosting where your site resides on its own server. The problem with dedicated hosting, though, is that it is both significantly more expensive and requires a certain level of IT know-how. With cloud hosting, you can have many of the advantages to dedicated hosting without most of the challenges.

Scalability: With Cloud Web Hosting you can Access Resources you Need as you Grow


One of the primary advantages to cloud web hosting is its scalability. Visualize a group of clouds. Your website is being run in these clouds but it suddenly gets busy. You can gather more clouds around your site to help support it so your users see no degradation of services. However, if you no longer need the additional clouds you can let them float away. Sites that have spikes in resource use can benefit from this option.

Example: Joe owns a website that specializes in downloadable Christmas projects for children. Coloring templates, origami tree ornaments, story ideas and craft projects are all available for use during the Christmas season. Of course, his website is open all year round but he only has a busy season starting in late November, falling off in January. Once the holiday season starts Joe sees an increase in traffic. Near the second week in December his site is visited so often and items are downloaded continuously causing a strain on his shared host's server. His account is suspended and he has to scramble to get his site back up and running on a dedicated machine.

Joe now experiences downtime affecting his customers all for one small portion of the year where he experiences heavy traffic. With cloud hosting, though, he can increase his site's available resources and use what he needs. When his traffic decreases again in January, he can release those resources and run his site efficiently on only what he needs.

Immediacy: On Demand use for Additional Services Helps you When you need it


When you need additional resources you do not have time to wait for customer service to assist you by increasing your bandwidth allotment if needed. If you really have a spike in resources then you risk having your site suspended for causing degradation in services to other sites on your shared server. You may experience down time or slowness on your site caused by the increased traffic. But with cloud web hosting you can increase your available resources immediately, when you need it. This can save you a lot of stress and may even save some customers because the process is seamless. Customers or users on your site will not see any change.

Savings: With Cloud Web Hosting you Only pay for what you use, Saving you a lot of Money


It used to be that when you outgrew your shared hosting environment that your only other option was to move to dedicated hosting. However, this cost a lot of money. For the web site that did not need all the resources available on a dedicated server or did not need them all the time such as in the example of Joe above, the money spent was wasted on unused services. However, with cloud hosting what you pay for is the resources you use. When you no longer need them you release them and you are no longer charged for them.

Scalability, immediacy and savings allow you to efficiently run your website. You can grow and shrink the available resources per your needs. You can get what you need when you need it and you only pay for what you use. This allows you to concentrate on what you know best - running your website. You won't have to worry about your hosting solution.

Web Hosting, Compare Web Hosting, Web Hosting Reviews, Web Hosting Guides

Whether you have a personal site that you use simply to blog on occasion or a global, large scale business, security is of utmost importance. Security is likely the aspect of web hosting that is most important to everyone, and if it is not, it should be.

Lack of security can be devastating to a business if these problems result in loss of income or identity theft. Thus, it is important to understand what aspects of security you should look for and how to determine if your host provides security adequately.

Why is security such a growing problem?


The Internet is accessible to everyone and it is becoming the preferred means of conducting business. Whenever there is a possibility of exploiting a system for the gain of disreputable people, it will be attempted. The Internet is ripe for the taking and criminals will try many approaches to get what they want.

There are literally billions of dollars that go back and forth on the Internet and if these funds can be diverted to a thief, then they will attempt it. This is why consumers are so concerned with security and why you should look at security as a primary concern when choosing a host.

Who are you protecting your site from?


There are essentially two types of people who are out to do harm to your site. The most common and most threatening is the identity thief. This is the person who looks for an opportunity to gather information for personal gain. This sort of criminal is often an operating in a stealth capacity. They try to continue unnoticed for a long duration to maximize the number of victims they can access.

Not everyone who is out to harm your site is trying to steal from you. There is a significant group of hackers who are simply looking to cause disruption. When you are the victim of one of these hackers it can cripple your site causing prolonged down time and a loss of revenues. They typically wreak havoc for the sake of their own fun or to prove to themselves they can disable an organization and they usually work in a hit and run mode. They often put "graffiti" on the site, changing the page to let you know they were there.

What security issues should you consider

Luckily most web hosts are aware that there is a demand for robust security and they are listening to the demands of their customers. However, if you are not sure what to look for you may think you are not at risk. There are two things to consider. First, you need to be sure your web host is taking care of their servers to provide a secure environment. Next, they should provide the necessary tools to ensure you can secure your site and its functionality.

When searching for a new web host or evaluating the security of your own host here are some things to consider:

◉ SFTP - If you have ever uploaded files to your hosting account you are likely familiar with FTP (File Transfer Protocol). You use an FTP client to drag your files to where you want them uploaded and they will be published to your account. SFTP is the same concept but it is more secure. SFTP stands for Secure File Transfer Protocol and it provides an additional layer of protection. FTP, while fairly secure, is still vulnerable. Files can be intercepted and even modified with little to no indication. SFTP closes this vulnerability. Check to make sure this option is available to you via your web host.

◉ SSL - SSL stands for Secure Sockets Layer. SSL provides an encrypted path between the browser and web server. You can tell if an SSL certificate is being utilized with the indication of a locked padlock symbol on the address bar along with the use of https:// in the address as opposed to http://. If you run an Ecommerce site an SSL certificate is a necessity. It will help prevent customer information from being stolen. Credit card or banking numbers, name, address and other personal information will remain secure. Whenever you need to gather personal, sensitive information an SSL certificate is a must.

◉ Backups - Backups should be performed regularly in order to protect your site in case of a problem or disaster. Most hosts provide a tool in the control panel that allows you to back up your own site. This should be done and you should not rely on your host to do so. However, a host that has sound back up procedures is a plus. Check to see how often the host backs up their servers, what method they use and where backups are stored.

◉ Server maintenance - The web host should make sure the server is adequately maintained to ensure attacks are limited. Check to see if the host has a published security protocol which is a good (though not guaranteed) indication that they are on top of upgrades and patches.

VPS Web Hosting, Compare Web Hosting, Web Hosting Reviews, Web Hosting

VPS web hosting is one of the newer forms of web hosting that has only recently gained in popularity. VPS stands for Virtual Private Server. VPS hosting is a source of confusion for many individuals and businesses searching for a web host for their Internet ventures. The reason for this is that it really is a hybrid of shared hosting and dedicated hosting.

It is no wonder people are confused by the term and are unsure if it will suit their purposes and their web hosting needs. We shall look to clarify the pros and cons of VPS hosting to help you better decide if it is appropriate for your endeavors.

VPS Web Hosting Defined


A virtual private server is one that is partitioned so that it has its own operating system, disc space, and bandwidth. What, exactly, does this mean? A physical server that resides in a data center is used for VPS hosting. That server is then divided into various spaces that create its own virtual server. The account holder who is put on the virtual server sees only their virtual environment and can reboot their server or use it as if it was their own dedicated server.

The space acts just like a dedicated server but it is in actuality a part of one physical server. Because it acts as a dedicated server this is a good interim solution for sites that may need a dedicated server in the future but are not yet ready for it. VPS hosting is a good bridge between shared hosting and dedicated hosting.

Who Uses VPS Hosting?


Many hosting customers have a preference for VPS hosting because they have more control over their environment than they do with shared hosting. Even if they do not need all the system resources allocated to them in the VPS and a shared environment is just as suitable, the control they are afforded is worth the added expense.

For people who want to have dedicated hosting but are a bit wary of the technological knowhow needed, VPS hosting is a good starter package to get their feet wet. They can try it out and increase their skill set without committing to as much money up front.

What Are the Benefits of VPS Hosting?


As with all types of web hosting, there are pros and cons to each and each one is suited to specific circumstances. Generally there are many advantages to hosting your site on a virtual private server. These include:

◉ A VPS hosting account is less expensive than a full dedicated hosting plan that uses a physical server.

◉ Many VPS plans can be customized to meet your needs so you pay for what you want but you do not need to deal with any features you will never need.

◉ Many VPS hosting plans are easily scalable. You can start off in your virtual environment with the minimum amount of resources you need and then as you grow gradually increase your hosting plan to accommodate your needs. You do not have to pay for excessive resources you have not yet grown into.

◉ You have a lot more control over your virtual server than you do with shared hosting. You will likely have root access and the ability to use scripts that may not be allowed in the shared hosting environment.

◉ You have the same technical support as with shared hosting for most issues.

◉ You can choose from semi managed hosting where the web host handles some maintenance and fully managed services.

Are There any Disadvantages to VPS Hosting?


VPS hosting, in theory, is a great way to have the services of a dedicated server but without the cost associated with it. However, there are some potential issues that may occur with VPS hosting. The main disadvantage from a financial standpoint is that it is more expensive than shared hosting. For sites that do not need a dedicated hosting service, the cost may be prohibitive. While it is not as expensive as dedicated, it is also typically a lot more expensive than shared.

From a services standpoint, though, the issue can be a lot greater. Some web hosts offer VPS hosting but do not allocate the resources appropriately. This may cause problems down the line if a particular site uses its resources at peak levels. The reason for this is that the web host may have over sold its space, banking on the probability that each account on the physical server will not use its allocated store of resources. However, if they do, it may cause server issues that will affect all other sites on the server. A way to combat this is to ensure that you are aware of how many virtual accounts are on the server at one time.

VPS hosting is a great bridge between shared hosting and dedicated hosting. It s main advantage is the ability to have complete control over the hosting environment as you would get in a dedicated hosting package but without the cost. There are a few issues you may encounter if the host does not handle VPS correctly but if they do and you can afford the slightly higher price, it is a great option.

Website Security, Web Hosting, Compare Web Hosting, Web Hosting Reviews

Websites are always to prone to security risks. Cyber crime impacts your business by hacking your website. Your website is then used for hacking assaults that install malicious software or malware on your visitor’s computer.

Hackers may also steal important customer data such as credit card information, destroy your business and propagate illegal content to your users.

Security Considerations


Updated Software

It is mandatory to keep you software updated. It plays vital role in keeping your website secure.

SQL Injection

It is an attempt by the hackers to manipulate your database. It is easy to insert rogue code into your query that can be used to manipulate your database such as change tables, get information or delete data.

Cross Site Scripting (XSS)

It allows the attackers to inject client side script into web pages. Therefore, while creating a form It is good to endure that you check the data being submitted and encode or strip out any HTML.

Error Messages

You need to be careful about how much information to be given in the error messages. For example, if the user fails to log in the error message should not let the user know which field is incorrect: username or password.

Validation of Data

The validation should be performed on both server side and client side.

Passwords

It is good to enforce password requirements such as of minimum of eight characters, including upper case, lower case and special character. It will help to protect user’s information in long run.

Upload files

The file uploaded by the user may contain a script that when executed on the server opens up your website.

SSL

It is good practice to use SSL protocol while passing personal information between website and web server or database.

A website is more than a collection of web pages and Web management is a variety of things. Web management includes designing the website, along with various administrative tasks such as web security and picking the right web hosting service. While a lot of things goes into making a website up and running, web hosting definitely tops the list. To help you better understand, we break hosting down with an analogy that you can easily understand. Imagine you’re opening a new store, for which you need a name, a location, staff, and products. Even if one of these essential items is missing, your store cannot open. The same goes for a website.

The four basic elements required to get your website up and running are: the domain name, a web server, maintenance staff, and content. In the hosting world, the site name, otherwise known as the domain name, is the first thing that’s need to be decided before anything else. For the potential customers, the first reference they have to a business or organization’s online presence is its domain name. When a website starts gaining momentum, the domain name becomes a valuable entity. Thus, choosing a good domain name is a crucial decision for any business and it is mostly a marketing decision. So, it’s important to understand the difference between the two.

Web Hosting, Hosting Reviews, Hosting, Compare Web Hosting

What is a Domain Name?


A domain name is like an address where users can access your website. You cannot buy hosting and start designing your website until you have a domain name for the website. A domain name is the organization’s address on the Internet. It’s like an identity for finding computers on the Internet. It’s a name registered in the DNS that is universally identified by web servers and online organizations via the Internet. The DNS serves as the phone book for the Internet.  The Domain Name System (DNS) associate all sorts of information with domain names. Every computer on the Internet is uniquely identifiable by a DNS name that consists of a host name along with the names of all of its parent domains.

Web Hosting, Hosting Reviews, Hosting, Compare Web Hosting

What is Hosting?


After you choose a domain name and register it, the next step is to find a web hosting service. Web hosting is an Internet hosting service that allows your website to be accessible to the World Wide Web. A web hosting service provider has data centers and huge servers, through which it offers space and connectivity to its customers. The customers hire their services for hosting your data and website on their server. These services have special computers called as servers that are connected to the Internet. The servers are up and running 24/7 and store the HTML documents, images and other attributes associated with websites. Depending on the needs of your business, you can choose between a variety of web hosting services: free, shared, VPS, dedicated servers, and cloud hosting.

Difference between Domain and Hosting


Meaning of Domain vs. Hosting

A domain is an address where Internet users can access your website. It’s a name registered in the DNS that is universally identified by web servers and online organizations via the Internet. For the potential customers, the first reference they have to a business or organization’s online presence is its domain name.

Web hosting, on the other hand, is an Internet hosting service that allows your website to be accessible to the World Wide Web. Web hosting allows your site to be accessible to the world and your prospective customers available to the World Wide Web.

Function of Domain and Hosting

A domain name is the organization’s address on the Internet. You can’t buy hosting and start designing your website until you have decided on a name and have purchased the domain name. A domain represents an Internet Protocol address, an URL to find a website on the Internet. The IP address is a combination of numbers separated by dots.

The web hosting company rents you space on a computer connected to the Internet. It’s the responsibility of the web host service is to make sure the computer keeps working and the Internet connection stays alive all the time.

Services involved in Domain and Hosting

Domain and hosting are two different services that work together in conjunction to keep the website up and running. The Domain Name System (DNS) is decentralized directory that translates human-readable domain names such as www.wikipedia.org into machine-readable IP addresses like 192.168.1.1.

Web hosting services have data centers and huge servers, through which they offer space and connectivity to their customers. In addition, they also provide a variety of other features such as domain registration, email hosting service, internet connectivity, advanced security features, and more.

Overview


Web hosting is a service of providing online space for storage of web pages. These web pages are made available via World Wide Web. The companies which offer website hosting are known as Web hosts.

The servers on which web site is hosted remain switched on 24 x7. These servers are run by web hosting companies. Each server has its own IP address. Since IP addresses are difficult to remember therefore, webmaster points their domain name to the IP address of the server their website is stored on.

It is not possible to host your website on your local computer, to do so you would have to leave your computer on 24 hours a day. This is not practical and cheaper as well. This is where web hosting companies comes in.

Types of Hosting


The following table describes different types of hosting that can be availed as per the need:

S.N. Hosting Description 
1 Shared Hosting
In shared hosting, the hosting company puts thousand of websites on the same physical server. Each customer has their own allocation of physical web space and a set of bandwidth limits. As all websites share the same physical memory, MYSQL server, an Apache server, one website on the server experiencing high traffic load will affect the performance of all websites on the server. 
Virtual Private Server (VPS)
It is also known as Virtual Dedicated Server. It is a server that is partitioned into smaller servers. This customer is given their own partition, which is installed with its own operating system. Unlike shared hosting, VPS doesn’t share memory or processor time rather it allocates a certain amount of memory and CPU to use which means that any problem on a VPS partition on the same drive will not affect other VPS customers. 
Dedicated Server
In this kind of hosting, a single dedicated server is set up for just one customer. It is commonly used by businesses that need the power, control, and security that a dedicated server offers. 
Reseller Hosting
A reseller acts as a middle man and sells hosting space of someone else’s server. 
Grid Hosting
Instead of utilizing one server, Grid Hosting spreads resources over a large number of servers. It is quite stable and flexible. The servers can be added or taken away from the grid without crashing the system. 

Web Hosting Companies


Following are the several companies offering web hosting service:

S.N. Hosting Company
Blue Host
Go Daddy 
Host Gator 
just Host 
Laughing Squid 
Hivelocity 
liquid Web

What is DNS? Learn about its advantages and disadvantages


What is DNS? DNS is the Domain Name System, or the hierarchical system of nomenclature that orders the names of members who connect to IP networks, such as the Internet.

In this article we will briefly learn what DNS is, how it works, what it is used for and some of its advantages and disadvantages. What is DNS? Shall we begin?

What is DNS?


Although it also fulfils other “less popular” functions, DNS is a system that organizes web domain names and makes them more “intelligible” for all those who want to connect to the network.

As you probably already know, each of the devices that connect to the network has an IP number (Internet Protocol), which is the number that identifies that device as part of the network. It is something like what our physical address would be (our home address, for example), but in the network.

What happens with these numbers is that, like phone numbers, they are not usually easy to remember. They follow a structure like the following: XX.XXX.XX.XXX

And while it’s true that we usually remember or store phone numbers with a certain simplicity, imagine if you had to do the same with any web domain you wanted to access. The list would end up being endless and our management of the network would be much more cumbersome.

What is DNS? Let’s take an example.

Imagine you want to connect to Google. If there weren’t a system like DNS, every time you wanted to connect to Google you would have to search and type in a heavy string of numbers. And the same with any other place you’d like to access.

What the DNS system does is “to translate” the names we give to the domains to the IP language, so that the devices (client and server, in this case) can communicate satisfactorily without the need for us, as users, to know the IP numbers of each domain.

How does DNS work in practice?


DNS uses a hierarchical database that contains information about domain names.

If, for example, you try to access a web address from home, the DNS system goes through a whole series of steps.

Imagine that you make a request that requires a DNS search (for example, you type the name of a web page in the address bar of your browser). The first thing your computer will do is to send a request to the local DNS server of the operating system. This checks to see if the answer you need is in your computer’s cache (for example, if you’ve recently accessed that page, it’s likely that the information is still stored).

If it is not found in the cache, the request is sent over the Internet to one or more DNS servers, which will generally be those made available to its users by the Internet service provider you have contracted. If the required information is not found on these DNS servers either, the request will be sent to other external servers.

These are the steps that are followed, but how is the search structured? Let’s look at a key idea.

As we said before, the DNS search is hierarchical, and this is what explains the structure of domain names.

Domain names are divided into two or more parts, called tags, which are separated by dots. (For example, blog.xyz.org).

The right label is called the top-level domain (the “org” in the example). The following on the left are called subdomains, and the one on the left most often expresses the name of the machine (it does not refer to a particular physical machine). The DNS system will use all this information to rank your searches.

Some advantages and disadvantages of the DNS system


For all of the above, you can already assume that the main advantage of the DNS system is that it greatly facilitates the use of the Internet, which would be much heavier and more difficult if we had to know all the IP addresses we wanted to access. But it’s not the only one.

Another considerable advantage is, for example, the stability it provides. For different reasons, IP addresses (e.g. servers serving a web page) may change, so if you want to access a website you not only need to know the IP address, but this information should also be up to date. If we had to do it ourselves, we would be faced with a very laborious task. On the contrary, the DNS system is in charge of updating the IP addresses in a much faster and constant way, avoiding an important effort.

However, like everything in this life, the DNS system also has some drawbacks, such as those related to security. For example, there is the possibility of one of the famous “DNS attacks”, in which the attacker replaces the real DNS address with a fraudulent one, with the aim of deceiving users and directing them (without them knowing it) to malicious addresses, usually with very bad intentions, such as taking over their bank details or other sensitive data. In addition, there are other types of fraudulent practices, such as the creation of domains very similar to the real ones (for example, replacing the letter “l” in the name with the number “1”) that can mislead users and direct them to harmful websites.

Overview


WWW stands for World Wide Web. A technical definition of the World Wide Web is : all the resources and users on the Internet that are using the Hypertext Transfer Protocol (HTTP).

A broader definition comes from the organization that Web inventor Tim Berners-Lee helped found, the World Wide Web Consortium (W3C).

The World Wide Web is the universe of network-accessible information, an embodiment of human knowledge.

In simple terms, The World Wide Web is a way of exchanging information between computers on the Internet, tying them together into a vast collection of interactive multimedia resources.

Internet and Web is not the same thing: Web uses internet to pass over the information.

Evolution


World Wide Web was created by Timothy Berners Lee in 1989 at CERN in Geneva. World Wide Web came into existence as a proposal by him, to allow researchers to work together effectively and efficiently at CERN. Eventually it became World Wide Web.

The following diagram briefly defines evolution of World Wide Web:

Web Hosting, Web Hosting Reviews, Compare Web Hosting, Web Hosting Guides

WWW Architecture


WWW architecture is divided into several layers as shown in the following diagram:

Web Hosting, Web Hosting Reviews, Compare Web Hosting, Web Hosting Guides

Identifiers and Character Set

Uniform Resource Identifier (URI) is used to uniquely identify resources on the web and UNICODE makes it possible to built web pages that can be read and write in human languages.

Syntax

XML (Extensible Markup Language) helps to define common syntax in semantic web.

Data Interchange

Resource Description Framework (RDF) framework helps in defining core representation of data for web. RDF represents data about resource in graph form.

Taxonomies

RDF Schema (RDFS) allows more standardized description of taxonomies and other ontological constructs.

Ontologies

Web Ontology Language (OWL) offers more constructs over RDFS. It comes in following three versions:

◉ OWL Lite for taxonomies and simple constraints.

◉ OWL DL for full description logic support.

◉ OWL for more syntactic freedom of RDF

Rules

RIF and SWRL offers rules beyond the constructs that are available from RDFs and OWL. Simple Protocol and RDF Query Language (SPARQL) is SQL like language used for querying RDF data and OWL Ontologies.

Proof

All semantic and rules that are executed at layers below Proof and their result will be used to prove deductions.

Cryptography

Cryptography means such as digital signature for verification of the origin of sources is used.

User Interface and Applications

On the top of layer User interface and Applications layer is built for user interaction.

WWW Operation


WWW works on client- server approach. Following steps explains how the web works:

1. User enters the URL (say, http://www.want2host.com/) of the web page in the address bar of web browser.

2. Then browser requests the Domain Name Server for the IP address corresponding to www.want2host.com.

3. After receiving IP address, browser sends the request for web page to the web server using HTTP protocol which specifies the way the browser and web server communicates.

4. Then web server receives request using HTTP protocol and checks its search for the requested web page. If found it returns it back to the web browser and close the HTTP connection.

5. Now the web browser receives the web page, It interprets it and display the contents of web page in web browser’s window.

Future


There had been a rapid development in field of web. It has its impact in almost every area such as education, research, technology, commerce, marketing etc. So the future of web is almost unpredictable.

Apart from huge development in field of WWW, there are also some technical issues that W3 consortium has to cope up with.

User Interface

Work on higher quality presentation of 3-D information is under deveopment. The W3 Consortium is also looking forward to enhance the web to full fill requirements of global communities which would include all regional languages and writing systems.

Technology

Work on privacy and security is under way. This would include hiding information, accounting, access control, integrity and risk management.

Architecture

There has been huge growth in field of web which may lead to overload the internet and degrade its performance. Hence more better protocol are required to be developed.

The answer is- When you calculate the cost for personnel, Internet bandwidth, power, real estate, phone service, and air-conditioning; you will receive tremendous economies of scale as overhead cost is shared by the many customers in a Colocation facility – literally a fraction or the cost you would otherwise pay! With such large amounts of power usage comes a tremendous amount of heat, thus requiring special and very expensive air-conditioning units that you won’t find in a typical office building.

The colocation hosting services which are specifically designed for VOIP and businesses using it can be considered as the one of the redundant services. VOIP colocation services are provided to facilitate the more secured infrastructure resulting in cost saving. Taking many a things into consideration, in addition to having much better quality service, server colocation is much, much, less expensive and easier than trying to locate your servers within your office space.

One can reduce overhead costs using VoIP Colocation and Hosting services. Avoid the hassles of a phone room filled with expensive equipment that requires additional office space and personnel to manage. Save dramatically on power usage for cooling systems and the need for high bandwidth by taking advantage of the benefits of VoIP Colocation and Hosting services.

Colocation service providers generally provide the server colocation facility rather than VOIP colocation. But there are few service providers who provides such facility in order to make this convenient for the users. ”There are hundreds of companies offering server hosting and colocation, but generally very few offers services specifically for VoIP with direct access to their own carrier-class network. Since these servers are located in data center, they are looped directly into world class voice network providing superior latency and call quality.

Benefits of Server Virtualization


Virtual Server, Web Hosting Reviews, Compare Web Hosting, Web Hosting

Server virtualization has been in the trend for a couple of last years and it is a reality that knocks companies, bringing numerous benefits to all who seek the resource savings and a more effective IT management. Furthermore, it is a green technology.

Server virtualization is the concept of taking a physical server and, with the help of virtualization software, partitioning the server, or dividing it up, so that it appears as multiple “virtual servers,” each of which can run their copy of an operating system.

To give a broader view of server virtualization, here is a comprehensive list of advantages and disadvantages, which can be compensated by using a cloud provider with recognized market action.

Let’s check out the advantages and disadvantages of Virtual Server.

Advantages of Virtual Server:


1. Facilities to be simplified, space-saving, time and cost-saving.

2. Centralized management and Full compatibility with applications.

3. Greater availability and easier recovery in case of disaster.

4. The ability for running backups and can use multiple operating system environments on the same computer.

5. Controlled access to sensitive data and intellectual property by keeping them safe inside the data center.

6. Best use of space: the fewer physical devices installed, the greater the availability of space in racks.

7. Migrating servers to new hardware transparently.

8. Reliability and Availability – the failure of software does not affect the other services.

9. The cost reduction is possible using small virtual servers on a more powerful single server.

10. Adapting to different workloads, which can be treated simply. Typically, virtualization software reallocates hardware resources dynamically between a virtual machine and another.

11. Load balancing: the whole virtual machine is encapsulated. Thus, it becomes easy to change the virtual machine platform and increase its performance.

12. Support for legacy applications: when a company decides to migrate to a new operating system, you can keep your old operating system running in a virtual machine, which reduces the cost of migration.

13. Reduction of personnel costs, power, and cooling by using less physical equipment.

14. Better utilization of hardware – the hardware sharing by virtual machines is reduced to idle equipment.

15. Creates independent user environments. Keeping everything separate is especially useful for purposes like software testing.

16. Reduced downtime.

17. Ease of migration environments – prevents reinstallation and reconfiguration of systems to be migrated.

Disadvantages of Virtual Server:


1. The biggest disadvantage of virtual servers is that if or when the server goes offline, all the websites hosted by it will also go down. Hence, to solve this, the company could set up a cluster of servers.

2. Management – virtual environments need to be instantiated (create instances on virtual machines), monitored, configured and saved.

3. Difficulty indirect access to hardware, for example, specific cards or USB devices.

4. Performance – currently, there are no consolidated methods to measure the performance of virtualized environments.

5. When several virtual machines are running on the same host, performance maybe hindered if the computer it’s running on lacks sufficient power.

6. Huge RAM consumption since each virtual machine will occupy a separate area of the same.

7. It requires multiple links in a chain that must work together cohesively.

8. Great use of disk space, since it takes all the files for each operating system installed on each virtual machine.

The advantages and disadvantages of virtualization are a clear indicator that it can be a useful tool for individuals, entrepreneurs, and enterprises when used properly.

Dedicated Server, Web Hosting, Web Hosting Reviews, Compare Web Hosting

Work in modern organizations is difficult to imagine without a server. Without it, data is disjointed, is stored on different computers and even when using network, is quite difficult to pull together when needed for the job. And so what about a situation when database is in daily use? You could never do this without a server.

Previously, many organizations are saved on the server using this as a regular computer. They did not meet the main requirements for servers, but this was ignored in order to save. As a result, when the computer is denied, information is lost, which cost far more than it would cost a dedicated server. Or, if you need to increase the capacity of the system, had to buy a new computer, which is why, again, the economy turned out to be doubtful.

Performing even the simplest functions of the office server, such as mail-server, file / print server, shared Internet access, applications for small workgroups, the server for small databases, the personal computer is subjected to the voltage for which it is perfect. Mode without turning off the power for which it is not intended, wears all parts of the machine physically, and it may be said to be destroyed in one or two years. The velocity of its work is often a serious impediment to business. And in that moment when the personal computer “dies”, with it freezes all the activities of the firm, the entire database, all the contacts and stuff which was on the server. This can be compared with a small disaster for the company.

To solve a similar problem, a server specialized computer can be used that is designed for this purpose. But first,  to understand the difference between a server and personal computer is important.

First of all (and this is probably the most important) – the server differs a great in reliability. The fact that failures of servers come in two forms – one is planned when they take the technical work (maintenance, upgrades) and unplanned, when the server “lies”. In the first case, the server shuts down intentionally, in the most convenient time and usually in such cases, it does not bring inconvenience to users virtually.

The second case – the theme for the subject of conversation. The fact that most things on the server can be changed at run time and has only one element fail, the person who looks after it, right there, it should make a dead piece of labor. These details are most often going down the fans and power supplies (if not supported by redundancy), with hard drives and expansion cards. Thus, there will be no downtime. That is, unplanned downtime can occur only because of  IT-specialist, if he had not found problem on time and did not eliminate it, if one or more hard drives and so on are out of order. Moreover, until now there are companies where the leadership sees nothing wrong with that server is also a working machine programmer. This leads to the fact that the additional software installed is conflicting with the system, causing disruptions.

In addition, the server may refuse to work if it is subjected to intentional remote attack. It can be organized as a local area network and the Internet. Therefore, you must take care of server security.

In recent years, various databases are greatly developed, changing the format for storing and processing data, database servers came. File servers are only for storing user files and archives.

Increasingly, networks are now based on terminal servers. This system allows you to save users in the workplace, as all software and files are located on the server and the terminal can be a pretty simple machine. In addition, significant savings are achieved at the expense of installing and maintaining software. For serious work, it is important and acquired servers are much more carefully maintained.

Thus, buying a server and using it for its intended purpose, rather than establishing an ordinary personal computer, the company invests in its future, because this investment will pay for itself through increased productivity, saving time on maintenance and improving stability.

Colocation Services, Web Hosting, Web Hosting Reviews, Compare Web Hosting

Importance of Colocation Server


Every business works towards growth. As the internet presence of any business has now become the most crucial need, the need to use an efficient web hosting service has become their top priority. A growing business needs to use its own dedicated web server or servers to efficiently control the security and website operations, and the critical data management.

But at the same time, creating an efficient data center to host these servers can quickly pose lots of difficulties in managing it. A data center needs huge infrastructure costs, 24-hours on-site experienced technical and management support teams to manage all the data center requirements, servers, and data. It also needs very efficient cooling system, proper data-storage environment, climate-controlling systems like air-conditioners, complete fire protection, hyper speed connectivity, 100% uptime, round the clock monitoring of systems, redundant power supply, and security for all these systems, for example, using CCTV security surveillance systems, other security methods to prevent unauthorized use of the data center, among other such important things.

Needless to say, the best option for the business is to hire one of the best colocation services in close vicinity to be able to monitor the web servers when needed. However, it can be very difficult for the business to find a good colocation center without expertly knowing which one to select depending on the needs of its business requirements and the safety and management of its own web servers.

Architecture of Colocation Server

The following features should at least be looked for in a colocation service before making the choice to use their colocation services for your online business requirements, and moving your web servers to their data center. The initial scrutiny of any colocation service needs the following 5 factors to be checked:

Location Of The Colocation Services


Once the choice of a few selected colocation servers is made, it is better to opt for a colocation service that is closer to your place. This is because, as you will need to visit the colocation service’s data center to monitor and manage your server from time to time, it is better to choose the service that is within comfortable traveling limits. Although this may seem like a trivial matter, it is very important that you should be able to control your web servers and other equipment’s at all times.

Colocation Services’ Experience And Reputation In The Field


The colocation service should have many years of experience and should have services many businesses over that period of time. The colocation service must have a great overall reputation for the quality and reliability of its services. These 2 factors provide the information about the stability, reliability, expertise, and the risks-free nature of the colocation service provider.

Furthermore, checking for any bankruptcy filed by the data center helps tremendously as many top data center are in deep monitory troubles despite the fact that colocation is a growing business, and that fact can be found only if you look particularly for such details.

The colocation services must stay up to date on colocation advancements and should have the best infrastructure facilities, redundant power and cooling systems, experienced and efficient staff to manage all activities, security systems, experts in overall management of the data center, and other such things to help them become very reputable and become extremely reliable. With such a service, your servers are safe and you can expect a longer and very fruitful association with the colocation service.

Infrastructural and Staffing


Needless to say, the infrastructure of the colocation services and the staffing of expert technicians in the field are the 2 most important features of any good colocation service. The data center building must be built according to the prevalent high standards specific to this field with raised floors, ample space, better building materials, and maintaining the balance of the eco-system.

The essential services like the redundant power resources, redundant environmental control systems with perfect cooling systems, multiple fiber optic redundant and very high-speed global connections, and other such networking necessities must be present at the colocation service.

The maintenance and technical staffs that are highly experienced and experts in the field must be present 24 hours a day to overlook the management of the facilities and manage any problems instantaneously. There should be other staff present like expert managers, security staff, and other such members to take care of all other things besides the actual internet related services.

Connectivity Provided By The Colocation Services


Any top-tier data center offering colocation services must contain secure, remote, and upgraded colocation hosting facilities with high-quality fiber optic data network equipment’s. This ensures very high-speed reliable internet connectivity. Presently, the internet connectivity has managed speed of nearly 10 Gigabits per second. As the colocation services offer direct collectively to the internet using their own equipment’s, the need to hire other services is eliminated and the unrestricted and highest internet connectivity speeds are achieved.

This means greater power and a faster bandwidth for the business website owners that hire the colocation facilities. The redundant nature of the connectivity, power and cooling resources of the colocation services means unconstrained operations for the online businesses, resulting in nonstop and faster services offered by them to all their online users.

Colocation Service Fees And Terms Of Services


The best colocation services offer variety of top quality web services to their users usually at very affordable rates. But affordable rates alone do not imply great overall quality of the colocation services. Hence it is imperative to research for the best colocation service that offers top quality web services and also offers a great price that is affordable to the business organizations and also to the individuals who require colocation service.

The colocation services offer a variety of packages that can be upgraded at any time, and also include custom packages to enable the customers plenty of options to choose from and fulfill the needs of their websites and their budgetary allocations.

The terms of services are important too. It also means that a customer can hire the colocation services for a long time without requiring their servers and equipment’s to be shifted and new IP addresses to be procured in case they find the service has unsuitable or even unethical practices. Adhering to the proper terms of services from the beginning also eliminates avoidable any future legal proceedings and maintaining a good relationship between the colocation services and their customers.

So, these are some of the precautions that are necessary before choosing a good colocation service for placing your web servers and related equipment’s and acquiring high-end colocation services.

The server includes:

◉ Very fast processor
◉ Large memory
◉ Large capacity drives
◉ Connect to high-speed line T1 (connected to the outside world).

Hardware is hosted in very large office buildings or data centers. In rooms with climate control, the racks of dedicated servers are stored. Most servers can boast that they are in working order 99% of the time, and more. This impressive figure and one more reason to enjoy a host server. Remember how often you had rebooted my computer?

Software. (Operating System)


In the market there are different operating systems. It is possible that your server uses Apache, or Linux, the open source software. Dedicated Servers must be protected and the application of open source in most cases contain less bugs and more secure than their opponent – a product of Microsoft.

These servers provide an interface to access and configure them, the so-called control panel. Some of the panel are different from other more complex. Depending on your knowledge and skills in the technical field, should look for this circumstance when choosing a host.

Protocol. (FTP)


To send the page to the server you need it “loaded” by executing a file transfer protocol (FTP, file transfer protocol). FTP – a client (for you) application server. If you have created your Web page in your own desktop, it is obvious that in order to open this page for general use, you must download it to your server. FTP-protocol is also used to exchange files between your and other computers.

What is SSD?


SSD stands for Solid-State Drive. SSD has no moving parts. On the contrary, it uses flash memory to store data onto the drive. Owing to this, your drive doesn’t heat up, is able to read/write data at a faster rate, as well as, consumes less energy as compared to HDD (Hard Disk Drive).

What are the benefits of SSD:


There are several reasons for you as a business to opt for SSD based web hosting. Here are the top 5 benefits of SSD:

1. High Performance

In the SSD drive, the data is read directly from the storage area. Unlike HDD, there are no rotation heads or magnetic disks and hence the read/write rate of SSD drive is higher. This, in turn, improves the performance of SSD.

2. Hardware Reliability

SSD has no moving parts as there is no magnetic coating or read/write head. Hence, they are free of distortions. No moving parts also imply minimal breakage or wear out of the storage drive. Hence, SSDs are more reliable, as well as, efficient.

3. Faster Speed

SSD uses flash memory to store data thus, it performs 300% faster than HDD drive. These functions include Read/Write time, response time, file transfers, etc. Moreover, the time taken to boost SSD too is less as it takes barely 10-13 seconds.

4. Less Power Consumption

The average power drawn by SSD is less than 2W. This significantly reduces power consumption and saves energy, making SSD more environmentally friendly.

CPanel Hosting.,WHM Hosting, Web Hosting, Compare Web Hosting

After buying a web hosting package of choice, every user is given a tool to manage their hosting service. cPanel and WHM are two such tools that help users maneuver and take total charge of their web hosting.However, users who generally buy a web hosting package ask for both without knowing the exact functionality and purpose of cPanel and WHM. Which is why it becomes imperative to know the difference between cPanel and WHM. As you read further, you will understand what is the purpose and the difference between cPanel and WHM.

What is cPanel?


CPanel Hosting.,WHM Hosting, Web Hosting, Compare Web Hosting

cPanel is an online control panel that helps users manage Linux hosting service. With the help of cPanel, a user can control administrative tasks of hosting such as creating a website, creating and managing emails, resetting passwords, setting mail forwards, managing add-on domains and subdomains, uploading and managing files etc.

What are the key benefits of cPanel?


cPanel allows users to manage files with ease. Its simple GUI ( graphic user interface) acts as an enabler for managing system admins when you are not looking to use a website builder. This has made cPanel user-friendly in comparison to its peers and competitors. For the want of explaining its pluses in details, here is a list of the same:

◈ Allows you to add on domains and manage email according to hosting plans
◈ Gives control over FTP accounts to upload, delete or move files on the server
◈ Provides users with web related stats like visitors/month through AWS stats
◈ Numerous add-ons and APIs with Softaculous integration that allows users to download WordPress, Joomla or Drupal updates
◈ Ensures that your data is secure along with backup and recovery options; all this without compromising on scale
◈ Much economical in comparison to Windows

What is WHM?


CPanel Hosting.,WHM Hosting, Web Hosting, Compare Web Hosting

WHM (Web Host Manager) is an administrative access tool for the backend of the cPanel account. With WHM, one can create a cPanel account to avail hosting accounts. Users can easily manage many a light to heavy sites with the help of WHM. Moreover, one can sell hosting services and manage multiple cPanel with the option to modify, upgrade or even downgrade an account and monitor usage of bandwidth as well.

What are the key benefits of WHM?


WHM allows users to access DNS zones of all the domains. It also allows users to create, delete and suspend cPanel accounts. Apart from its ability to configure and support customer requests through the cPanel, it also allows users to change domain and usernames of clients. With a total backend control over cPanel, WHM has many other benefits for Virtual Private Servers and Dedicated servers as well. They can be enlisted as follows:

◈ WHM allows users to install and manage SSL certificates with ease
◈ It allows assignment and whitelisting of IP addresses
◈ With WHM, one can get access to all the accounts inside. In addition to this, it also allows one to change the ownership of the account in case an account is sold or deleted
◈ Clients can receive newsletters, updates and deal upgrades via WHM
◈ WHM allows other websites to brand themselves with different WHM skins
◈ It also monitors the status of the server and resources
On the whole, WHM takes away the time spent on server administration and puts the focus on managing requirements of customers.

What is the difference between cPanel and WHM?


Now that we know what role cPanel and WHM play, it will be easier for you to know what is the difference between cPanel and WHM. Or perhaps you have already figured it out with the information we gave you. Just to put things back into perspective, here are some main points that highlight the difference between cPanel and WHM:

Parameter WHM  cPanel 
Controller WHM is a Reseller control panel. It is used by resellers to manage all the hosting accounts of their reseller plans.  cPanel is the control panel used by the end users under a reseller of hosting provider. It is used by customers to manage their own hosting accounts. 
Access WHM provides resellers with root level access.  cPanel only provides access to web hosting account on the server to its users.
Port number WHM functions via 2087, a secure port number.  cPanel on the other hand functions via 2083 as its secure port number. 
Password reset Password details for WHM coincide with its cPanel account. I.e if you change the password of your WHM then the password of cPanel will also change.   The password for cPanel can be set by the end user as he or she wants. 
Domains One can only add domains and not subdomains.  Adding and removing add-on domains and subdomains is possible. 

cPanel and WHM have characteristics that are quite distinct from one another. Both of them work in tandem, but at the same time maintain a difference that benefits both end users and resellers. We hope that you have understood the difference between cPanel and WHM.
