A Service Mesh for Collaboration Between Geo-Distributed Services: The Replication Case
AbstractEdge computing is becoming more and more present, with sites geo-distributed around the globe. Applications on these infrastructures must be able to manage the latency and disconnections inherent to their distribution. One way to deal with these concerns could be to deploy one entire instance of the application per site and use a service mesh to manage the collaboration between the geo-distributed instances. More precisely, we propose to reify the location of application instances in REST requests and allow redirections between these requests thanks to a dedicated language and a service mesh allowing three types of collaborations. This paper focuses on the replication of a resource between multiple instances. Though it is still a work in progress, we demonstrated the relevance of our approach in the OpenStack ecosystem.
