An Efficient Redundancy Control and Load Balancing Scheme for Cloud Storage

With the rising popularity of cloud enabled storage, storage devices may not be uniformly presented in terms of software and hardware and combining them (particularly legacy systems). Existing solutions consider requirements across diverse infrastructures by promoting redundant replicas solutions that trade-off between scalability and access control. In this paper we propose a solution using the following three strategies: dynamic control over the number of replicas, load balancing on the basis of file access records, and data migration based on path prediction. We demonstrate the effectiveness of the proposed scheme using a comprehensive evaluation provisioning results of real-world analysis.
