Abstract. Cloud computing center energy consumption is enormous, it is important to enhance the energy efficiency of cloud computing industry. In cloud computing, computing tasks can migrate across data centers. At this point, the existing data center energy efficiency evaluation indicators can not reflect the actual energy efficiency of the computing center. Based on the existing energy efficiency evaluation index on the basis of calculation for multi center model is put forward for the migration of cloud computing center energy efficiency evaluation index of CDCeP, and based on this index, put forward by the mobile micro cloud computing center, chase new cloud physics of low cost and high efficiency of migrating Computing Center operation mode, effectively improve the cloud computing the center of the equivalent energy efficiency, reduce emissions.
