Live migration of containerized microservices between remote Kubernetes Clusters

The recent adoption of cloud native technologies by telecommunication industry is accompanied by the incoming development of Network Functions that are containerized and packaged as light-weighted microservices. In order to efficiently orchestrate Cloud-Native Network Functions (CNFs), thorough migration strategies should be supported to place and migrate the CNFs. In this paper, we present a testbed illustrating the migration of pods between remote K8S cluster. As a use case, we consider the migration of a network function belonging to an opensource 5G core network (namely, Magma).
