Kubernetes WANWide: a Deployment Scenario to Expose and Use Edge Computing Resources?
Résumé
Cloud Computing have highlighted the importance of container orchestration to manage distributed applicationy's life-cycle. With the advent of Edge Computing, DevOps expect to find the features of containers in the cloud, also at the edge. However, orchestration systems have not been designed to deal with geo-distribution aspects such as latency, intermittent networks, etc. In other words, it is unclear whether they could be directly used on top of massively distributed edge infrastructures without revision. In this paper, we provide an evaluation of Kubernetes in a WANWide context. Precisely, we present and discuss results we obtained during an experimental campaign to analyze the impact of WAN links on its behaviour. While there exist initiatives investigating Kubernetes revisions to deal with distribution aspects, there is, to the best of our knowledge, no rigorous performance evaluations to disqualify the vanilla code.
