Abstract: Efficient mapping of virtual machine request to the available physical machine is an optimisation problem in data centres. It is solved by aiming to minimise the number of physical machines and utilising them to their maximum capacity. Another avenue of optimisation in data centre is the energy consumption. Energy consumption can be reduced by using fewer physical machines for a given set of VM requests. An attempt is made in this work to propose an energy efficient VM placement algorithm that is also network affinity aware. Considering the network affinity between VMs during the placement will reduce the communication cost and the network overhead. The proposed algorithm is evaluated using the Cloudsim toolkit and the performance in terms of energy consumed, communication cost and number of active PMs, is compared with the standard first fit greedy algorithm.
Keywords: virtualisation; affinity aware; cloud computing; virtual machine placement; network affinity.
