A Light-weight Data Replication for Cloud Data Centers Environment
Unlike traditional high performance computing environment, such as supercomputers, the cloud computing is a collection of interconnected and virtualized computing resources that are managed to be one or more unified computing resources. The Cloud environment constitutes a heterogeneous and a highly dynamic environment. Failures on the data centers storage nodes are normal rather than exceptional. As a result, the cloud environment requires some capability for an adaptive data replication management in order to cope with the inherent characteristic of the Cloud environment. In this paper, the authors propose a data replication strategy to adaptively select the data files which require replication in order to improve the availability of the system.
