title: Is it possible to run akka system with both transport enabled netty and artery?
body: <p>Is it possible to run two applications with different transports (netty/artery) and make them communicate each other?
  For example:
  If system A is listening tcp port (netty) and system B listening udp port (artery), can we send message from B to A?</p>
  
  <p>When I've tried to create an actor ref on system B like this:
  <code>system.actorFor("akka.tcp://akka-2-5@127.0.0.1:2525/user/actor-2-5")</code></p>
  
  <p>I've got error: <code>java.lang.IllegalArgumentException: Wrong protocol of [akka.tcp://akka-2-5@127.0.0.1:2525/user/actor-2-5], expected [akka]</code></p>
  
  <p>So, looks like I need to configure my actor systems to start with both transport systems. But how can we do this?
  I'm looking for a way to send messages with single actor system and different akka transports (netty or artery) as different micro-service neighbors can use different transports.</p>
