Here you can chose Top Rated Web Hosting Services Compared

Selecting the right web server is considered very crucial decision in online business. It is due to the fact that the web server can either make the business or can even destroy one’s business.

There are two types of servers, one is Virtual Web Hosting and the other is Virtual Private Servers.

Since several years Virtual Web Hosting has been the only way to go when selecting a web server. One of the reasons for the Virtual Web Hosting’s popularity is that they supports the necessary files and allows one to have more freedom than any other conventional web hosts. But now one can have more freedom than ever before with Virtual Private Servers. However, Virtual Private Servers should not be confused with Virtual Hosts, as they both are entirely different from each other.

In this article the difference between a Virtual Host and a Virtual Private Server is explained. Moreover the advantages and disadvantages of both the servers are also explained in order to give understanding as to which server should be chosen for business.

Virtual Hosting

Virtual Hosting is also known as Shared web hosting, where one can share the physical server and a single set of software applications with other users. Virtual Hosting was very popular in the past due to features like fast deployment, strong resources, and attractive price. Another advantage offered by Virtual Hosting is that it provides a powerful, reliable, and professionally managed server and it can be easily handled without having to have advanced technical skills, thus making it ideal for an individual, small business, or even a fresher webmaster.

The greatest disadvantage of Virtual Hosting is that the server is shared with other users, which are configured and even controlled by an administrator, not user. Thus there is no control in the hands of the users and in case of adjusting or setting configuration one have to contact the administrator every time. Even if one manages to get a hold of the administrator, then also they may not fulfill the request. It’s all up to them as they are the administrator. Thus these are the limitations faced by users when control is not in their hands.

Virtual Private Servers

Virtual Private Servers are very popular now days for giving the good and satisfactory results. A Virtual Private Server is a single server that is partitioned at the root into multiple dedicated servers. This enables one to share the cost of the network connectivity, hardware, and system maintenance with other hosting customers, with maintaining the flexibility and freedom.

The most important advantage of Virtual Private Servers is that they allow complete control to users and they have security advantages of a dedicated server at very low cost. Thus one can have access to the virtual root, Telnet, web configuration files, and full CGI-BIN access. Not only that, they also provide access to one’s password and send mail configuration files to their users. Thus after considering above advantages it can be concluded that a Virtual Private Server is an excellent solution for small to medium size businesses having complex requirements.

However, there is one disadvantage with Virtual Private Servers, i.e. one need to have some program knowledge in order to control and configure the settings. But this advantage is also evaded by most businesses that offer Virtual Private Servers as they provide detailed manuals making them easier to configure and control. Thus no need to learn the programs as well.

Now one can decide which server is right for him/her. However it all depends on user’s requirement as well as the size of your network.

If one plans on having just one web site and have absolutely no programming knowledge, for him/her Virtual Hosting serves as a best as its quite economical as well. A Virtual Host costs around $20 to $50 per month for an account, as against a $100 or more charged by a Virtual Private Server.

On the other hand, if one is having a larger network requiring multiple web sites and user is having some programming knowledge, then a Virtual Private Server can serves a best. One can host up to 50 web sites on a Virtual Private Server account, instead of having multiple Virtual Hosting accounts, which is quite expensive.

Thus one must make sure while selecting a server that it is as per requirement and it supports essential software for a flourishing online business.
