Towards Dependable Emergent Ensembles of Components: The DEECo Component Model

Abstract—In the domain of dynamically evolving distributed systems composed of autonomous and (self-) adaptive compo-nents, the task of systematically managing the design complexi-ty of their communication and composition is a pressing issue. This stems from the dynamic nature of such systems, where components and their bindings may appear and disappear without anticipation. To address this challenge, we propose employing separation of concerns via a mechanism of dynamic implicit bindings with implicit communication. This way, we strive for dynamically formed, implicitly interacting groups – ensembles – of autonomous components. In this context, we introduce the DEECo component model, where such bindings, as well as the associated communication, are managed in an automated way, enabling transparent handling of the dynamic changes in the system.
