Virtualization is the act of creating a virtual rather than actual version of something, including a virtual computer hardware platform, operating system, storage device, or computer network resources, and more.

Virtualization software essentially turns one computer into several. It can be applied to servers, desktops and applications. Server virtualization allows you to run multiple virtual machines on a single physical server. Desktop virtualization allows you to run multiple desktop machines on a single physical server, and distribute them. Application virtualization allows you to distribute multiple copies of an application from a single physical server.

The reason virtualization is such a hot topic with businesses of all sizes, is because it delivers a number of tangible benefits:

System Security: Because individual operating systems running on a virtualized machine can be isolated from each other, virtualization can create secure machines.

Save Time: Backing up and restoring virtual systems is much less time-consuming than doing so on several individual machines. Additionally, hardware failures will not affect virtual machines in the same way they would a physical machine.

Operating System Services: Virtualization lets you take advantage of the capabilities offered by different operating systems on just one set of hardware.

Save Energy: The energy costs of running a server in a datacenter can be more than the server. Virtualization is a good way to reduce operating costs.

Multicore Processors: Virtualization software can allow users to directly assign groups of processor cores to individual operating systems.

Software Testing: The ability to run two or more operating systems side-by-side means that programmers can test new releases of software without the need for dedicated machines. If software corrupts an operating system, a parallel operating system running on the same computer can still be used for development.

Virtualization has the potential to greatly streamline your organization's IT infrastructure and operational workflow. If you are interested in bringing it into your organization check out PC World’s 10 Steps to Get Started with Virtualization.
