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.
