简介
Cloud computing has emerged as a main approach for managing huge distributed data in different areas such as scientific operations and engineering experiments. In this regard, data replication in Cloud environments is a key strategy that reduces response time and improves reliability. One of the main features of a distributed environment is to replicate data in various sites such that popular data would be more available. Whenever a site does not have a needed data file, it will have to fetch it from other locations. Therefore, the parallel download approach is applied to reduce download time. It enables a user to get various parts of a file from several sites simultaneously. In this work, we present a data replication strategy, named the Dynamic Popularity aware Replication Strategy (DPRS), which is presented on Cloud system leveraging data access behavior. DPRS replicates only a small amount of frequently …
