Have you checked out DC/OS? It's built on Mesos/Marathon/etc. and has some pretty cool service discovery/routing built in, i.e. Minuteman which allows you to define virtual IPs and ports that map to specific services.

Haven't tried DC/OS. Been using the open source solutions with custom glue code around it.
