The long latency on reading the files from remote node of cloud storage leads to degrade the whole system service performance and waste the network resource. In order to improve the speed of data access, replica management ability and optimize the whole system performance, the dissertation proposes a replica replacement strategy based on gravitational search model, which can achieve the goal by removing unnecessary replica, inactive replica and updating replica. The simulation results show that the presented method is effective and reasonable.
