There are several different kinds of hosting solutions available in the market these days. One of these hosting solutions is Virtual Private Server Hosting. A virtual private server or VPS is a hosting solution that makes use of virtual servers to host websites. This means that in case of a VPS plan there are several virtual servers running on the same physical server; with each virtual server being used as a hosting account.
VPS hosting plans are considered better than shared server hosting plans simply because of the performance improvement that is achieved by making use of dedicated resources. In the case of a VPS plan, the server resources are allocated statically to each of the virtual servers running on the server. What this means is that every hosting account has some resources assigned to it and these cannot be shared by any other hosting account on the server. This is not the case with shared web hosting plans wherein server resources are shared dynamically.
The advantage of such a configuration is that no single website hosted on the server can hog all the resources and cause a performance degradation for other websites on the same server; something that is somewhat regular in case of a shared hosting plans.
Another thing that is really good about a VPS plan is that you have the freedom to install any application or plug-in on your server without having to worry about the dependencies with other installation on the server. This is because everything you install would be run on a virtual machine (VM) that is specific to your account and runs in a sandboxed environment that is not affected by any other changes done on the server outside of the VM’s scope.
Security is always a big consideration while choosing a web hosting plan. Let me tell you one thing, a VPS plan is as secure as a dedicated server hosting plan. The reason for this being the use of virtualization concepts which logically separate environments from one another and do not allow execution of procedural calls of one environment in another environment. Although, some procedures might be implemented in shared server hosting environments to disallow cross execution of procedures, but those procedures might not be that effective and may leave out security loopholes.
One more thing that makes a virtual private server hosting more desirable is the cost associated with running such a plan. Virtual private server hosting plans are only marginally costlier than a shared web hosting plans but offers features that are comparable to a dedicated server. Hence, it becomes a very good choice if one is looking to leverage high end hosting features at a cost that is only a little more than a comparative shared web hosting plan.
Thus, it can be said that a Virtual Private Server is one of those plans which can be used as an upgrade option to a shared web hosting. Not only this, since the features of such a plan are comparable to those offered by a dedicated server; such a plan can be a great option for those looking for a hosting solution that offers the features and the freedom offered by a dedicated hosting but do not have the kind of money that is required to run such a plan.
