The capabilities of Cyber-Physical Systems (CPSs) are increasingly being extended towards new composite services deployed across a range of smart sensing and controlling devices. These services enable the emergence of multiple end-to-end cyberphysical scenarios, formed dynamically based on their demands, e.g., disaster recovery systems. In such scenarios, each cyberphysical flow may be composed of a large number of physical services with composition challenges such as high dynamism of CPS

Cloud computing enables new perspectives in the design and operation of CPSs, including consolidating and sharing physical services among different applications, auto-scaling computing and communication, and designing and maintaining multiple in-Cloud CPSs dynamically at the same time. In this paper, we present a new architectural approach to address the key concerns of a new generation of CPS services whose functionalities reside in-Cloud (cyber), and on devices and systems (physical). In particular, this design space is focused on principles that allow in-Cloud evolution of CPS services, including dynamic in-Cloud service composition and distribution, virtualization of physical services and devices, and the dynamic creation of CPS ecosystems. In this design model, the in-Cloud cyber part may evolve independently, while the ondevice cyber and physical platform still work closely together and provide the basic CPS services.
