Affinity Aware VM Colocation Mechanism for Cloud
The most of the existing Virtual Machine (VM) placement algorithms do not consider the affinity i.e. dependency between the virtual machines. Also, in many existing virtualized systems it is found that the network bandwidth often becomes the bottleneck resource which can lead to the performance degradation of the applications deployed in the cloud. In this paper, the authors present an affinity aware VM colocation mechanism for cloud. The proposed mechanism find out the network affinity between the virtual machine pairs and co-locate the virtual machine pairs having higher network affinity on the same physical host.
