Eco-Aware Online Power Management and Load Scheduling for Green Cloud Datacenters
Many of today’s cloud datacenters are powered by electricity generated from brown energy (e.g., fuel fossil, oil), which directly translates into severe harm to the environment. To reduce the carbon footprint and the operating cost of datacenters, there is a clear trend to migrate to green datacenters, which are entirely (or partially) powered by renewable energy. However, given a portfolio with multiple off-site and on-site power supplies (such as power grid, renewables, batteries, etc), it is challenging for datacenter operators to conduct efficient power management and thus meet the highly dynamic user demand. In this paper, we proposed an online algorithm, called EcoPower, to perform eco-aware power management and load scheduling jointly for geographically distributed cloud datacenters. Our objective is to minimize the time-average eco-aware power cost of cloud datacenters while still ensuring the quality-ofexperience constraint of user requests. To this end, we formulate the p...
