Load Balancing Strategy for Migration in Virtualized Data Center

Abstract

Virtualization techniques provide the carving individual physical servers into multiple virtual containers that can be run and managed separately. However, due to the uncertainty of workload variation, the workloads may be unbalanced in the virtualized system, leads to application’s SLA violation. In order to deal with such problem, the mathematical expectation approach use to determine the hotspots in virtualized server. To relocate virtual machine (VMs) from overloaded servers to underloaded ones, the system uses the Balance migration to reduce the migration cost and it eliminates the hotspots.
