| Abstract: | For the problem of energy consumption in Cloud Computing data centers, this paper puts forward the theory of Green Cloud Computing and designs a green cloud system architecture. Based on the green cloud system architecture, the energy is considered as system resources to achieve resource allocation. Three green task scheduling algorithms are proposed and respectively named as the STF-OS, LTF-OS and RT-OS algorithm. The feasibility analysis of three algorithms is made with the relevant theory and shows that three algorithms can effectively reduce energy consumption. The simulation is set on the CloudSim by extending Cloud Computing platform. The results show that the STF-OS algorithm has the most optimal ability of the reducing energy consumption of data center. |
