The cost of power is going up all the time. It is now thought to be the major cost of running a data centre and data centre power efficiency can reduce IT costs significantly. Indeed, a significant data centre can consume as much power as a small city act. Virtualization is an approach which allows multiple operating system instances to run concurrently on a single computer. So power consumption is less. But Today Cloud computing Environments have to provide good Quality of service which deals with power performance issues. This Paper defines the efficient use of resource management policy for cloud infrastructure. Power consumption can be decreased by Live Migration of VMs. Here, the authors discussed about VM selection policy based on power deduction approaches.
