Toward Low-Cost Workload Distribution for Integrated Green Data Centers

This paper aims at maximizing the utilization of green energy and cutting the cost of electricity associated in provisioning computing services across a group of data centers. To this end, we propose the notion of green workload and green service rate, versus brown workload and brown service rate, respectively, to facilitate the separation of green energy utilization maximization and brown energy cost minimization problems. Accordingly, a workload distribution algorithm is designed such that the cost of electricity is reduced as compared with the existing workload distribution schemes.
