Inter-cloud data persistence in DIL networks

Cloud computing garners wide use by the information technology industry. Multiple cloud instances can now be configured to synchronize persisted data. Communicating internally and between cloud instances generally requires a modern networking infrastructure. However, some networks are severely constrained by their environments with disruptions, intermittent connectivity, and limited bandwidth. These types of networks are known as DIL networks. Employing cloud technologies in these environments remains difficult. We analyze current cloud data persistence techniques operating in a simulated environment where intra-cloud communications use a reliable network and inter-cloud communications operate over an unreliable DIL network. The results suggest that cloud technologies can be used effectively for data persistence across a subset of DIL networks. However, improvements will be necessary to support more constrained environments.
