Energy Efficiency in Virtualized Cloud Environment

Abstract

Dynamic virtual machines (VMs) provide services in a cloud environment. The manner the VMs allocated to PMs influences the efficiency of cloud applications and resource competence. By using VM migration techniques, it is viable to move the VMs on from over-utilized physical machines (PMs) to under-utilized PMs ensuring the stable load on all PMs using virtualization technology. This research article illustrates the Live VM migration in the cloud system. The importance of energy efficiency in the CDC, VM Migration Process, performance metrics that are used to evaluate the efficiency of Live VM migration, and comparative analysis of VM migration techniques is also highlighted.
