Cloud computing provides flexible resources to users through utility based computing that is paid per usage model. Virtualization stands as a key enabling feature of cloud computing. Resource needs are not static due to the diversity of applications and need to manage resources dynamically. To achieve dynamic resource management there is a need to increase the performance of resource allocation for different resources requested by the client through better allocation of virtual machines to the host, performing the migration of a VM from one host to the other. Server consolidation is done to power off the least utilized nodes when the workload concentration is fewer in certain nodes to reduce the carbon emission. This approach increases the utilization of cloud resources even in idle periods by forming virtual clusters.
