Manish B. Gudadhe, Avinash J. Agrawal · 2017
Data replication in cloud computing emerged as a popular alternative to the traditional cluster based replication because of the exponential growth in usage of the internet with an explosion of data sources and usability of data. To provide high data availability, improved performance and sustaining growing demand of data, cloud paradigm became a popular platform for replication of the frequently used data. This research article mainly concentrates on the availability of replicated data in the cloud under various situations. The variations in popularity of content, the number of replicas, placement of replicas, distribution of data nodes and workload will be analyzed to their impacts on the serviceability and data availability. The paper will investigate replication strategies based on heterogeneous cloud storage, explosive query load outburst, network bandwidth and varying content popularity. This work is an attempt to provide a comparative analysis of performance under different values of number of replicas, network bandwidth and content popularity.
