Requirement bottlenecks in a cloud based SCADA system

High expectations of the cloud hold great promises for computer scientists and engineers. However, its applications in realtime systems, especially in SCADA, are still in infancy stage. Besides, while there were a lot of researches working on integrating scientific systems on cloud systems, even the study on the mentioned topic was limited. Therefore, the authors seek to address some major issues in creating a cloud compatible realtime SCADA system. These are: data storage and database management, security of a system hosted on the cloud and system failure and recovery on the cloud.
