An over-utilization avoidance host selection scheme for affording workload of migrated VM

During the conservation of energy in Cloud Computing, server consolidation comes as a well-known process to achieve maximum utilization of resources with the least number of servers active. In this process of server consolidation, the Virtual Machine (VM) migration acts as the backbone where VMs are made to transfer the workload from one server to the other, provided Quality of Service (QoS) does not get compromised. While performing the act of migration, the selection of host on which the VM workload is to be transferred needs to be chosen intelligently such that performance is not degraded. This paper henceforth proposes a host selection scheme for the migration process avoiding over-utilization of a host by using median of medians algorithm as base.
