Simulating Communication Processes in Energy-Efficient Cloud Computing Systems

Cloud computing data centers are becoming increasingly popular for the provisioning of computing resources. The cost and operating expenses of data centers have skyrocketed with the increase in computing capacity. In this chapter, we survey the main techniques behind enabling energy efficiency in data centers and present simulation environment for energy-aware cloud computing. Along with the workload distribution, the focus is devoted to simulating packet-level communications in realistic setups. Finally, the effectiveness of common power management solutions is assessed and a scheduling methodology that combines energy efficiency and network awareness is presented.
