Towards a Resilient Control Architecture for Combined Fog-to-Cloud Systems

The capacity to efficiently manage the whole set of resources from the edge up to the cloud paves the way to a new landscape of innovative opportunities for all involved actors, be it on the research or industrial sides. Fog-to-Cloud (F2C) has been recently proposed as a management solution particularly tailored to manage the stack of resources from the edge up to the cloud in a coordinated way. However, beyond the benefits brought by considering all the spectrum of resources to run a service, resilience, as a concept must be reflected in the F2C design. In this paper, we address a particular scenario where a specific node failure in the F2C architecture will substantially impact on the whole system performance, and analyse three tentative strategies to efficiently manage such scenario.
