Abstract:
With the advent of virtualization technology, multiple
heterogeneous virtual machines (VMs) can be coexisted
on a physical server. Dynamic allocation of server’s
resources prevents over provisioning and under
provisioning which is caused by fixed allocation.
Moreover, live migration helps movement of VMs when
the host has not enough resources. In order to address on
demand provisioning and give migration decisions, an
efficient resource management system, LIBRA is
presented in this paper. Fuzzy based methods are applied
to both of the cases. According to the experimental results,
we can say that LIBRA is an efficient resource
management system for virtualized data center.
