The main limitation for building cloud infrastructures is their energy consumption. Moreover, their conception is

Cooling costs can be reduced by intelligent scheduling, and in our case through virtual machines migrations. In this paper, we propose a dynamic reconfiguration based on evolution of temperatures and load of the servers. The idea is to share heat production to reduce cooling costs and consolidate the workload when possible to reduce servers costs. The challenge resides in satisfying these opposite objectives. We tested our algorithm on an experimental testbed, and achieve to cap the temperature of the datacenter room while not forgetting to optimize the server use, and without impacting on applications performance.
