Benefits Of Server Virtualization

Server virtualization is a method by which software is utilized to partition a single physical server  into multiple computers that are known as virtual machines. To the user, the virtual environment appears as if it is its own standalone piece of hardware. In data centers and IT departments, virtualization is utilized to better utilize server resources. In general, a physical server only uses 20 percent of its capacity. By hosting several virtual machines on one physical server it’s possible to improve hardware utilization upwards of 80 percent. For IT managers and data centers, this also means reducing hardware costs upfront, and reduced TCO in the long run.

A smaller, much more efficient data center means reduced costs in cooling and heating, and less equipment to maintain. Website hosting companies, refer to virtualized servers as virtual private servers or virtual dedicated servers.
Although even just several years ago the costs to implement virtualization made it prohibitive for small to mid-size businesses, today, virtualization is most often a smart, sensible and cost effective option for businesses of all sizes. You don’t need a fancy expensive data center to implement virtualization!
More  and more businesses are moving to the cloud. Cloud Hosting Companies can deploy virtual servers, for your company’s use,  on their physical servers in their data centers.  Hosting clients receive many of the same benefits of virtualization as  those who implement on-premise data centers and IT departments.  Hence, many companies are making the move towards Cloud Computing.

However, in a hosting environment, shared hosting, where a number of different web sites are hosted on one single physical server,  is the most typical  type of deployment. form of website hosting. Although shared hosting provides many of the benefits of virtualization, and in some sense may be regarded as a specialized type of virtualization, an even better option is the deployment of what is known as a Virtual Private Server, or VPS.


With shared hosting the end user has little choice over what software is pre installed and little control over whatever web sites are hosted on the server. On the other end of the spectrum we have dedicated hosting, where a client rents a physical server for their exclusive use. For a hosting client dedicated osting enables provides the most resources and control, however, it’s much more expensive than shared hosting.
A Virtual Private Server provides many advantages over both shared hosting and a dedicated server. It is more expensive than shared hosting, but considerably less expensive than dedicated hosting, with almost the same level of functionality and performance. A VPS also provides the client with a great deal of control over the environment. The client can control which operating system and software the server runs, no matter what software environment is running on other partitions inside the server.


In a VPS environment, although some basic software runs on the physical server to maintain partitions, firewalls, along with other security, the end user is basically unaware of anything outside the virtual machine they’re interacting with. Although the virtual server shares physical space with some other virtual machines, server virtualization is safer than shared hosting, because it effectively functions to provide you with an isolated and separate computer. With shared hosting there exists the possibility that your performance will be negatively impacted by other web sites on the shared server, or that other users could gain access to your data through security breeches.  Although a VPS is a less affordable hosting option than shared hosting, it is usually a fraction of the cost of dedicated hosting.
