Hi Artyom, I am not too familiar with the new Play 2.4, but I think you could write a provider <https://github.com/typesafehub/project-doc/blob/5971b305e905db03c06929a0fadb7c0a574d94cd/app/modules/ConductRDocRendererModule.scala> for your User actor that would use ClusterSharding(system).shardRegion(UserRegion.shardName)to create ActorRef.
