Green Cloud and Virtual Machines Migration Challenges

Abstract

This paper presents a green design of VM manager and migration controller which are important components of the green data center framework. In traditional cloud data centers, designing VM managers are based on the highest availability with maximizing active physical servers to decrease the down time of VMs, but in contrast, we try to meet the highest availability with minimizing active physical servers. The result will be reduction of energy consumption. Thus, to reduce energy consumption in data centers, there are different solutions for designing a VM manager and a migration controller for green data centers. The proposed method changes traditional view for designing VM manager to green VM manager by designing a VM manager and a migration controller as a one component and pointing out the challenges we should consider in new a VM manager and migration controller design. Also the green method helps data centers to reduce costs that have benefits for the cloud service providers. Keywords: Green Computing, Green Data Centres, VM Manager, VM Migration Controller
