Review on data replication strategies in single vs. interconnected cloud systems: Focus on data correlation‐aware strategies

Résumé

Data replication is a well-known technique in cloud systems for enhancing availability and performance. Various strategies and surveys have been proposed in this respect. These surveys include comprehensive analysis and classifications.However, to the best of the authors’ knowledge, there is no survey concentrating on strategies designed for interconnected cloud systems. In this article, we provide an in-depth analysis of existing data replication strategies in cloud systems, covering single and interconnected clouds.We also highlight data correlation-aware strategies as well as their key steps. Furthermore, we examine the major strategies’ features such as: (i) addressed replication issues, (ii) orientation towards the provider and the consumer, (iii) consideration of the service level agreement, (iv) consideration of cost and economic aspects, and (v) evaluation tools. Finally, we provide a performance analysis through extensive simulations of several replication strategies dedicated for single and interconnected clouds.
