Geographic Trough Filling for Internet Datacenters

To reduce datacenter energy consumption and cost, current practice has considered demand-proportional resource provisioning schemes, where servers are turned on/off according to the load of requests. Most existing work considers instantaneous (Internet) requests only, which are explicitly or implicitly assumed to be delay-sensitive. On the other hand, in datacenters, there exist a vast amount of delay-tolerant jobs, such as background/maintenance jobs. In this paper, the authors explicitly differentiate delay-sensitive jobs and delay tolerant jobs. They focus on the problem of using delay-tolerant jobs to fill the extra capacity of datacenters, referred to as trough/valley filling.
