Improved energy-efficiency measurement model for cloud computing

An energy efficiency measurement model was proposed to address the large-scale computing problem through two metrics: "energy" and "efficiency".As for "energy",the energy consumption of computer,network and affiliated equipments was considered;as for "efficiency",that of CPU,memory,disk and network was considered.The proposed energy efficiency measurement model describes the definition and mathematical expression of the improved energy efficiency measurement,and is proved reasonable through experiments.The energy efficiency of CPU intensive,I/O intensive and interactive computing was evaluated and analyzed based on the measurement model,and the energy efficiency laws in MapReduce environment were summarized.
