Recently, there are some problems in the centralized management, such as centralized management, heavy burden, excessive number of virtual machine migration, lack of mutual cooperation mechanism between nodes, can't adapt to the cluster of change. Aiming at the limitations of centralized management method, this paper presents a distributed management method in cloud computing environment. The method achieve self-management node by using P2P thinking. According to the predetermined threshold

... themselves decided to create a virtual machine, virtual machine migration and whether sleep to save energy consumption and other operations. This topology can be well adapted to large-scale changes in the cluster. The experimental results show that the distributed management method not only can effectively improve the quality of service, and can well satisfy the clusters of massive growth. It has a good robustness.
