Virtualization at the network edge: A technology perspective
Syed Rameez Ullah Kakakhel, Lauri Mukkala, Tomi Westerlund, Juha Plosila · 2018
Container-based virtualization offers a very feasible alternative to heavyweights like KVM or XEN. Containers are lightweight and offer near-native performance. They are also easy to deploy because of continuous integration/development tools and environments. This paper offers a brief introduction to containers, defines its properties and provides use-cases in the context of those properties. Secondly, we look at the live migration of stateful applications via containers. Live migration is a promising technique at the network edge to unload computing to other nodes to expand the use of fog computing / mobile-edge computing. Our experiment shows that live migration of stateful applications can result in three different types of errors, namely, resend, reprocessed and wrong-order errors.
