ACCORDION D2.3 - Architecture design (I)

This deliverable provides an account of the work done for the specification of the ACCORDION ecosystem architecture, which is mainly comprised of two artefacts: the infrastructure to support the cloud-edge continuum and the platform to manage the resources and the applications hosted in that infrastructure. The main outcomes of the work described in this deliverable are: a) the definition of components that comprise the architecture as well as their interactions, and; b) the assignment of the implementation of those components to specific project Tasks and partners. The deliverable describes the process for reaching to those outcomes, starting with the delineation of the scope of the described artefacts and working down to their specifics. The main approach used is the analysis of the platform use case scenarios. In practice, we analyze the scenarios and extract the required functionality. Then we cluster and map this functionality to components. Finally, we schematically present the interactions of those components using block and sequence diagrams. These outcomes are then validated against the use case requirements, especially those linked to the applications operation itself. This is meant to provide a proof-of-concept that the ACCORDION architecture is able to support the ACCORDION applications.
