Functional View of the Continuum Reference Architecture: Minimum set of expected functionalities


This is the second document of a series of three defining a reference architecture for the continuum. In the previous one, different building blocks were identified setting the path for the different aspects to be taken into account while defining the architecture. The next step is, then, to develop a functional overview of this reference architecture from this big picture to a more complete one providing the basic information to understand the interconnections between the abovementioned building blocks.
Functional architectures are needed to properly understand how a system acts and interacts. This is even more relevant within the continuum, as the gap between IoT and edge/cloud must be covered. In this sense, the work already performed aims to go one step further of other available architectures tackling one or two pillars of the continuum, by integrating the three of them totally agnostic of the application domain, that is, not influenced by any vertical or potential use case but flexible enough to address most of their needs.
This paper focuses on the minimum set of functionalities needed for the continuum lifecycle management as well as the relationships between them, providing different diagrams representing each of the initially identified building blocks and their interrelationships, with the main goal of developing the homogenised version of the Reference Architecture for the continuum.


This work was performed by Task Force 3: Architecture leader, part of the OpenContinuum project consortia, within the EUCloudEdge initiative.
Task Force 3 aims to provide a common vision on Continuum computing, providing a homogenised language and a reference architecture to set the basis for a European standard, positioning Europe ahead of the competition. The work presented here has been further validated with 30 ongoing research projects in the fields of edge, cloud and IoT (mainly ICT-40-2020, ICT-50-2020, ICT-56-2020, HORIZON-CL4-2021-DATA-01-05, HORIZON-CL4-2022-DATA-01-02, HORIZON-CL4-2022-DATA-01-03, HORIZON-CL4-2022-DIGITAL-EMERGING-01-26 and HORIZON-CL4-2023-DATA-01-04) and will be extended in the coming months until the reference architecture is fully developed and mapped with all projects’ solution architectures.
