The transition from centralized cloud computing models to the computing continuum paradigm has redefined IT infrastructure management requirements, introducing unprecedented complexity in the areas of orchestration and network security. Typical continuum scenarios are inherently characterized by a plurality of heterogeneous providers operating within a framework of mutual distrust. In this context, traditional security models are obsolete: executing workloads in shared environments requires the definition of granular isolation perimeters, not based on nodes as was previously the case. Moving beyond the now outdated logic based on physical nodes, this approach aims to mitigate the risk of compromise and inhibit unauthorized access. Although Kubernetes has established itself as the de facto standard for resource abstraction, it lacks the concept of federation natively, making it necessary to use external tools to enable peering between separate clusters.
