Abstract:
Abstract—A recent trend of server consolidation using virtualization has allowed datacenters to improve their server utilization rate and total energy efficiency. Virtualization technologies are used to share physical hardware between multiple services. This has led to another challenge: how to place the virtual servers into the physical servers? Especially, this is important in cases in when the workload of virtual servers is not constant. In this paper, we study the overhead of virtual server migration in physics computing on energy efficiency with an emphasis on quality of service. Our method is based on the standard migration technique that allows us to move virtual machines between physical machines without significant interference on the service running on the virtual machine. Our results indicate that by utilizing dynamic resource sharing among the virtual servers and load balancing between heterogeneous physical machines, it is possible to improve energy efficiency of online cloud services.
