Since few servers run at full capacity, virtualization uses some software and memory techniques to leverage the speed of the server processor(s) to host multiple virtual servers on one physical server. Just as one Windows personal computer can run multiple applications at once, server virtualization allows one physical server to run multiple copies of a server operating system. This offers great value by reducing the number of physical servers needed, reducing hardware and supporting energy costs.
