Power-aware game for cloud computing: A distributed mechanism based on Game Theory for minmizing power consumption in cloud scale datacenter

The power consumption of datacenters has increased dramatically in recent years. Cloud computing accelerates this increase. The reduction of power consumption has become a challenge for cloud providers in large scale datacenters. They consolidate servers by virtualization technology as an effective remedy for huge power consumption. The management of consolidation often has been performed centrally in datacenters. We devised a distributed self-organized mechanism based on Game Theory for this purpose. In the worst case, our results are only twice as great as the theoretical minimum power consumption. In addition our mechanism could enhance the current centralized ones in two ways. Firstly, it can make decisions with less delay in response to dynamic behavior of usage patterns in cloud computing. Secondly, it can better scale up in pace with the future datacenters.
