title: Path-based routing to external resource with AWS Application Load-Balancer (ALB)
body: <p>I have a working domain, x.y, which is tied to an EC2 instance on a VPC.</p>
  
  <p>I want a path on that domain, x.y/z, to be routed to an external, non-AWS (IPv4*) microservice. Can this be done with ALB?</p>
  
  <p>I have followed <a href="http://docs.aws.amazon.com/elasticloadbalancing/latest/application/tutorial-load-balancer-routing.html" rel="nofollow noreferrer">Use Path-Based Routing with Your Application Load Balancer</a> to set up target groups, but can't seem to link them to anything past EC2 instances?</p>
  
  <p>(*: Would be great to extend with ports, or even (sub)domains, paths, etc.)</p>
