Cloud Storage Architecture with Meta-Data Service Layer in Cloud Computing

With the rise of cloud computing, cloud storage has become a challenging issue. It is a huge challenge to design a distributed file architecture to meet the requirements of cloud storage. In this paper, in order to improve the system reliability and performance, we propose a cloud storage architecture with a meta-data service layer. The proposed architecture is a distributed file storage system based on the master-slave architecture, which uses multiple proxy servers of the meta-data server to establish a peer-to-peer meta-data service layer. Each meta-data server and the proxy server, could be an access to service for clients rather than only one fixed access as usual, which can improve the parallel processing performance of a meta-data service layer greatly. Some P2P techniques are used between proxy servers to solve the disadvantages of the master-slave architecture efficiently. Analysis and evaluation are performed to demonstrate that the proposed architecture improves the system reliability and performance greatly.
