Cyber-Physical Systems (CPS) [1] are key building blocks of the fourth industrial revolution. They consist of ICT systems that are embedded into the physical objects we manipulate daily and are interconnected through a complex network, to provide a wide range of innovative applications, resulting from the bridging of the physical and virtual worlds. The management of islands of CPS, which are currently geographically distributed in different countries and regions worldwide, is a challenging issue that will be of interest to both IT researchers and practitioners in the future. The challenge of moving massive datasets between locations of interest, while ensuring the secure transfer of these datasets, is another issue that needs to be resolved in order to get useful insights from the information embedded in these datasets. Therefore, the federation of these isolated digital infrastructures is a natural extension of the body of research that has been produced on CPS for the last decades. This talk focuses on the design and performance evaluation of Federated Cyber-Physical Systems (FCPS) [2,3,4,5,6] with the objective of showcasing through two use-cases how federated cloud computing (FCC) systems and federated machine learning (FML) [5,6] algorithms can be deployed as key FCPS components to build QoS-aware and privacy aware data-intensive ecosystems. Building on the two use-cases, the talk reveals that i) FCC can improve the quality of service delivered by data-intensive infrastructures through cooperative sharing of cloud resources, and ii) by moving data analytics close to where the data resides, FML can protect these infrastructures from attacks while simultaneously preserving the privacy of their data.
