With the continuous development of computer technology and network technology, cloud computing develops rapidly. Virtual machine migration is an important means of managing in cloud-based data centers. Two virtual machine migration models are constructed in this paper, the dynamic double threshold hotspot decision model and the destination choice model based on matching degree taking the availability of cloud data center services and the reduction of energy consumption into account. Based on the proposed model, a dynamic double threshold hotspot host decision algorithm and a destination host choice algorithm based on matching degree are adopted to guarantee the service quality of the cloud data center and reduce its energy consumption. At the same time, the algorithm of selecting the maximum relevant virtual machine is implemented. Finally, the classical migration algorithm and the algorithm proposed in this thesis are simulated on CloudSim. throught the comparison and analysis of the results, it is proved that the algorithm proposed in this paper can guarantee the service quality of cloud data center and reduce energy consumption greatly.
