Server virtualization is drastically changing how computing is done. Migrating physical servers to a virtualized environment can deliver efficiency gains and cost savings by increasing the utilization, manageability and availability while lowering hardware acquisition and ongoing hardware costs. Virtualization technology simplifies IT so that companies can leverage their storage, network and computing resources to control costs and respond faster. The virtual infrastructure approach to IT management creates virtual services out of the physical IT infrastructure, enabling administrators to allocate these resources quickly and to the highest priority applications for the business needs that require them the most.
