Managing Non-functional Requirements in an ELASTIC Edge-Cloud Continuum

The ELASTIC European project addresses the emergence of extreme-scale analytics, providing a software architecture with a new elasticity concept, intended to support smart cyberphysical systems with performance requirements from extreme-scale analytics workloads. One of the main challenges being tackled by ELASTIC is the necessity to simultaneously fulfil the non-functional properties inherited from smart systems, such as real-time, energy efficiency, communication quality or security. This paper presents how the ELASTIC architecture monitors and manages such nonfunctional requirements, working in close collaboration with the component responsible for the orchestration of elasticity.
