Communication-aware and energy-efficient resource provisioning for real-time cloud services

Operating expense of data centers is a tremendous challenge in cloud systems. Energy consumption of communication equipment and computing resources contributes to significant portion of this cost. In this paper, an online energy-aware resource provisioning framework to minimize the deadline miss rate for real-time cloud services is introduced. Communication-awareness is also taken into consideration in order to reduce energy consumption of the network equipment. A wide range of simulation results, based on real data clearly demonstrates noticeable improvement of energy consumption while at the same time the deadline miss rate is less than 1.5% in average.
