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.
