Integration of FogBus2 Framework with Container Orchestration Tools in Cloud and Edge Computing Environments

Currently, due to the advantages of light weight, simple deployment, multi-environment support, short startup time, scalability, and easy migration, container technology has been widely used in both cloud and edge/fog computing, and addresses the problem of device heterogeneity in different computing environments. On this basis, as one of the most popular container orchestration and management systems, Kubernetes almost dominates the cloud environment. However, since it is primarily designed for centralized resource management scenarios where computing resources are sufficient, the system is unstable in edge environments due to hardware limitations. Therefore, in order to realize container orchestration in the cloud and edge/fog hybrid computing environment, we propose a feasible approach to build a hybrid clustering based on K3s, which solves the problem that virtual instances in different environments cannot be connected due to IP addresses. We also propose three design patterns for deploying the FogBus2 framework into hybrid environments, including 1) Host Network Mode, 2) Proxy Server, and 3) Environment Variable.
