In recent years, the technology of cloud computing has been widely applied in e-business, e-education and etc.. Cloud computing platform is a set of scalable large-scale data server clusters, it provide computing and storage services to customers. The cloud storage is a relatively basic and widely applied service which can provide users with stable, massive data storage space. Our research shows that the architecture of current cloud computing system is central structured one, all the data nodes must be indexed by a master server which may become bottle neck of the system. In this paper, we propose a new cloud storage architecture based on P2P and design a prototype system. The system based on the new architecture has better scalability and fault tolerance.
