Research on Energy-Efficiency Model and Measuring Approach for Cloud Computing
Abstract:This paper presents an improved energy efficiency model and measuring approach for cloud computing.Cloud computing system energy efficiency was comprehensive evaluated through measuring the “energy” and ”efficiency”.As for “energy”,the energy consumption of computer,network and ancillary equipments was researched; As for “efficiency” , the relationship among CPU,memory,disk,network and energy consumption was researched.The I/O of memory,disk,and network should be or not to be incluced in the amount of effective task was mainly analyzed.Thus,a more comprehensive energy efficiency model was proposed and the energy efficiency of the mathematical expression is derived,the foundation for the optimization of energy efficiency was laid.
Key words: cloud computing; energy consumption; energy efficiency model; energy efficiency measuring
