Now-a-days, cloud computing is very popular for offering services over the Internet. The very important advantage of cloud computing is the ability to provision resources on demand. This avoids the problems of over-provisioning and under-provisioning which are commonly seen with organizations that have widely variable requirements due to increase/decrease, seasonal high and low workload etc. Resource allocation policies decide the amount of resource to be allocated to a particular or set of Virtual Machines (VMs).
