title: When to use local vs remote actors?
body: <p>When should I use Actors vs. Remote Actors in Akka?</p>
  
  <p>I understand that both can scale a machine up, but only remote actors can scale out, so is there any practical production use of the normal Actor?</p>
  
  <p>If a remote actor only has a minor initial setup overhead and does not have any other major overhead to that of a normal Actor, then I would think that using a Remote Actor would be the standard, since it can scale up and out with ease. Even if there is never a need to scale production code out, it would be nice to have the option (if it doesn't come with baggage).</p>
  
  <p>Any insight on when to use an Actor vs. Remote Actor would be much appreciated.</p>
