Challenges Towards Elastic Power Management in Internet Data Centers

Data Centers are energy consuming facilities that host Internet services such as cloud computing platforms. Their complex cyber and physical systems bring unprecedented challenges in resource managements. In this paper, we give an overview of the resource provisioning and utilization patterns in data centers and propose a macro-resource management layer to coordinate among cyber-and-physical resources. We review some existing work and solutions in the field and explain their limitations. We give some future research directions and the potential solutions to jointly optimize computing and environmental resources in data centers.
