Cloud data centers improve CPU utilization of their servers (Physical Machines or PMs) through Virtualization (Virtual Machines or VMs). Over virtualized and under virtualized PMs suffer performance degradation and power dissipation respectively. In this paper, system that uses virtualization technology to allocate data center resources dynamically based on application demands and support green computing by optimizing the number of servers in use. Thus minimizes the hardware cost and saves the energy and used when a system under a heavy load thus improves the system performance.
