I'm not sure if you can totally replace the lightweight BEAM processes with k8s equivalents. Sure if throwing more resources to scale more horizontally is not a top concern for you, then it probably doesn't matter much. But BEAM does make things much more efficient and less costly in general. Also, message-passing and the actor model is not a particular design focus of k8s compared to BEAM.
