It would be great if we could provision a single load balancer for a range of domains and request paths and configure rules within the load balancer to route the request to the appropriate place...
domain.com => droplet1, droplet2,
sub.domain.com => droplet1, droplet2,
sub.domain.com/api => droplet3
other-domain.com => droplet2
This way trying to balance a large number of low traffic sites which a single load balancer instance could easily handle across a pool of droplets with sites existing on 2 or more droplets would be possible natively.
