Hi, as you are well aware, running multiple separate Akka clusters increases operational/administrative burden for your application. Of course some applications need to run in separate clusters because of security / compliance constraints. But other than that, the more idiomatic way would be running a single Akka cluster and using cluster roles to manage how many instances of each service are active. I also think ShardRegion in proxy mode fits your use case very well.
