Benefits of Virtualization
● Consolidation and Increased utilization● Power/Cooling Savings (Green IT)● Leverage new technologies ● Rapid provisioning● Manage risks and minimize costs● Extend legacy software lifecycle● Dynamic software and hardware fault tolerance● Reduction of system admin hours to hosts ratio
