Cloud computing has already became one of the most sought-after center topics in the global IT industry, not only IT companies and the famous Internet enterprise, but also in each fields related to computer and the Internet are research and apply the cloud computing. The technology related to Cloud computing has also changed. This paper presents a hybrid P2P network model in the environment of cloud computing, defines the model, research and design the structure of the model, using DHT algorithm located the resource of Hash ring and analyzed the ring node in-and-out in detail. Finally, using the related mathematical theory deduce the performance evaluation results that the model of node can be hierarchical classification, improve the efficiency of information positioning and searching.
