Modeling on Energy Consumption of Cloud Computing Based on Data Center

this paper puts forward the monitoring and measurement methods on energy consumption of virtual machine in the cloud data center, establishes energy consumption model of virtual machine system and virtual machine migration. The usual migration method of virtual machine uses heuristic algorithm to allocate virtual machine, its solution result is easily to be got into locally optimal solution, and this paper gives migration algorithm of virtual machine based on genetic algorithm on the basis of making research on genetic algorithm, it makes improvement on the target function in genetic algorithm, making application number of target node and migration time minimum on condition of meeting protocol of service class, so that it can realize energy conservation in data center.
