You could but I don't think it would be the best tool for it. When I think of Akka, I'm using it because I don't want to worry about which node in my cluster any given actor is on, I just want to be able to scale horizontally and messages are routed appropriately.

Akka embraces the "let it fail" mentality where as nodes go down (just as pods go down in Kuberentes), you don't have to worry about where your processes are running...they just are...somewhere.
