Power Efficient VM Consolidation using Live Migration- A step towards Green Computing

From past the researchers have seen a brusque changes advent in the field of research areas on maturing the energy efficient large computational resources. Here firstly the basics of Cloud Computing discussed and then green computing with its architectural elements, power efficiency, live migration are presented. A novel Green computing framework is applied to the Cloud in order to meet the goal of minimizing the power consumption. This paper tries to impose efforts on power management with Live Migration. In Live Migration a running VM is moved from one physical host to another. Live migration is attractive to data center providers because moving a VM across distinct physical hosts can be leveraged for a variety of tasks such as power management, maintenance, or fault tolerance. Power consumption has found to be critical come forth in Cloud environment. Also servers take much energy to finish their tasks. Green computing comes up to overcome the energy consumption problem in cloud computing.
