Power efficient virtual machine migration in a scientific federated cloud

摘要

Virtualization technology enables cloud computing to provide virtual infrastructure. This virtual infrastructure is managed by centralized entity which is responsible for creation, deletion and migration of the virtual machine. Migration module helps to reduce the energy consumption using server consolidation which means multiple underutilized virtual machines can be deployed on a single physical machine. In such an environment, migration module moves the virtual machine from one host to another host to improve utilization. Therefore, migration algorithm plays an important role in the management of virtual cluster and power consumption. In this paper, we have proposed a slot-based migration approach to manage the virtual infrastructure using space-sharing technology of virtualization with the solution of multiple hops problem. The experimental results show that the migration module reduces considerable amount of power consumption.
