Event-Driven Digital Twins

The adoption of Digital Twins (DT) as a paradigm to realise a pervasive softwarisation of the physical world, across different application domains and different network levels (from cloud to edge), calls for software architectures and platforms featuring levels of flexibility beyond the ones provided by the solutions available in the state of the art. In this paper we introduce an architectural blueprint and implementation for an event-driven notion of DT, meant to tackle such limitations by promoting flexibility and decoupling. As validation, we present its conceptual application to the challenging context of healthcare emergency missions management and initial experimental evaluation through open-source DT solutions.
