Abstract
Nowadays, all modern IT technologies aim to create dynamic and flexible environments. For this reason, InterCloud has been designed to provide a vast and flexible virtualized environment in which many clouds can interact with one another in a dynamic way. Disaster recovery is one of the main applications of InterCloud which can be supported by Cluster as a Service. However, the previous studies addressed disaster recovery and Cluster as a Service separately. In addition, system backup and disaster recovery methods are not sufficiently effective in InterCloud. In this paper, we propose an InterCloud system which integrates both Cluster as a Service and disaster recovery in a harmonious manner. Also, we present a heuristic approach to select the best locations for system backup and disaster recovery in InterCloud systems. Finally, the proposed system is modeled and analyzed using Continuous-time Markov chains.
