Firstly ,Rational planned all resources in cloud data center to optimized allocation resources . Then, Combined with users ’ request .Cloud server agents allocated resources to cloud users . After achieve this two stages’ algorithm, it solve the problem of low resource utilization and low cloud service provider gains in cloud data center. At last , Compared with the
