Server virtualization allows organizations to run multiple virtual servers on a single physical machine. All virtual servers share the resources of the one physical computer.
How Does Virtualization Work?
A single or small number of physical servers can be used in place of many servers by virtual server software. This software provides an environment where many virtual servers can run on one physical server, reducing hardware costs while providing protection against hardware and software failure.
The virtual servers can respond to changing conditions and errors without affecting other virtual servers on the physical host server. In addition, should one physical server in a cluster of servers fail, the other physical servers can automatically take over its responsibilities. This provides for a high degree of both reliability and flexibility.
