There is a movement to configure Akka-Cluster on Kubernetes and build a system that is resilient and scalable. Because Akka is a toolkit for developing distributed applications across nodes, it requires orchestration capabilities such as deployment scaling at the container level. In that sense, Kubernetes is now a viable option. EKS has just arrived in the Tokyo region, so I think this kind of interest will grow. This time, I would like to discuss how to do real Event Sourcing on EKS and what problems there are by looking at the actual working code.
