How to scale out a Phoenix application with websocket

Foreword

It's relatively easy to scale out stateless web applications. You often only need a reverse proxy. But for those stateful web applications, especially those applications that embeds websocket services in them, it's always a pain to distribute them in a cluster. The traditional way is introducing some external services like Redis to handle pubsub, however, in such way, you often need to change your code. Can Erlang/Elixir, the "concurrency oriented programming languages", best other languages in this use case? Has Phoenix framework already integrated the solution of horizontally scaling websocket? I'll do an experiment to prove (or disprove) that.
