Energy-aware resource management and green energy use for large-scale datacenters: A survey

Abstract

As cloud computing gains a lot of attention that provides various service abilities, large-scale datacenters become dominant components of the cloud infrastructure. Huge energy consumption appears to be nonignorable leading to significant cost and also bad impacts on the global environment. How to efficiently manage the services while keeping energy consumption under control is an important problem. According to the analysis of prior representative literature, this paper makes an overview of energy-aware resource management approaches. The basic architecture of cloud datacenters and virtualization technology is introduced. Then, we conduct a survey of energy-aware approaches for adaptive resource management of such cloud environments. We also focused on some studies of renewable energy usage for green datacenters. Finally, the research problems are summarized and analyzed synthetically and possible future directions are given.
