Cloud cyber-physical systems are the natural evolution of embedded systems based on trends which may be observed in various domains. Cloud-based systems may be understood as a transformation of legacy system hardware and software architecture into more flexible, robust, powerful, and reliable solution. Cloud cyber-physical system (CPS) is the extension of the well-known CPS concept where complex computations may be moved to a cloud platform. We proposed the solution which benefits from utilization of OPC UA standard. This standard provides rich expressivity for data model design as well as for secure communication, data subscription, and triggering methods. The overall approach is demonstrated on proposed and implemented Semantic Big Data Historian which forms together with a cyber-physical system the implementation of cloud CPS concept.
