Abstract: Multi-access Edge Computing is booming as a promising paradigm to push the computation and communication resources from cloud to the edge to provision services and to perform computations. With container technologies, mobile devices with small memory footprint can run composite microservice-based applications without the time-consuming backbone transmission. Service placement at the edge is of importance to put MEC from theory into practice. However, current state-of-the-art research does not sufficiently take the composite property of services into consideration but study the to-be-placed services in an atomic way. Besides, although Kubernetes has certain abilities to heal container failures, high availability cannot be ensured due to heterogeneity and variability of edge sites.
