Recent cost analysis shows that the server cost still dominates the total cost of high-scale data centers or cloud systems. In this paper, the authors argue for a new twist on the classical resource provisioning problem: heterogeneous workloads are a fact of life in large-scale data centers, and current resource provisioning solutions do not act upon this heterogeneity. Their experiments show that their solution could save the server cost aggressively with respect to the non-cooperative solutions that are widely used in state-of-the-practice hosting data centers or cloud systems: e.g., EC2, which leverages the statistical multiplexing technique, or Right-Scale, which roughly implements the elastic resource provisioning technique proposed in related state-of-the-art work.
