Interoperability in large scale cyber-physical systems

While the capability for growing on demand is the design foundation of the new generation of software platforms, physical systems always have limited resources. Therefore, there is a need to optimise the existing infrastructures and evolving them building on interoperability. The optimisation of the infrastructure entails not only addressing the computational and storage capabilities but also the network, its associated intelligence and the exchanged information. Therefore, the interoperability requirement in a large scale cyber-system spans from the lowest layers, interfacing with the physical resources, to the software building blocks, client devices and handled data. In this paper, several initiatives addressing interoperability among cloud IaaS layers, IaaS-PaaS, PaaS-SaaS, Cloud-Network and data are presented.
