Comparative Analysis of the Mechanisms for Energy Efficiency Improving in Cloud Computing Systems
We consider a cloud computing system with three different mechanisms for increasing the energy efficiency of cloud computing systems. We investigate how energy efficiency of a cloud system is affected by a waiting time before a server goes to switch on/standby mode and threshold-based switch. We developed four mathematical models of Cloud computing system in terms of the queuing system and derived the system of equilibrium equations, which makes it possible to obtain the energy consumption indicators.
