A Systematic Review of Live VM Migration Techniques for Energy Management

Abstract

The present computing era has been inclined towards providing services to the customers all round the clock and is driven by utilization of existing resources in its entirety to assist service providers in extracting maximized profits. The key technique in achieving the automated services despite of geographical locations is creation of virtual machines using virtualization hypervisor. Though it entails several benefits of increased resource utilization, but it faces challenges of energy mitigation and related migration overheads originated due to balancing of load on the physical servers, fault handling in VM or server, transfer of irrelevant data, etc. If the total time and energy invested in every single VM migration can be minimized, it can give better results in term of energy consumption, total downtime, and migration time. Thus, the paper outlines a detailed review about various components of VM migration along with existing techniques and related aspects.
