Well, adding a library for supporting SRV records is not simple... If you use Weave [1], it gives a unique IP address to every service instance and a DNS record, all with zero configuration. That means you just stick any service in whatever default port it has, and it's all good. You can also have round-robin load balancing through DNS for free.

The performance penalties seem pretty significant at least as of a few months ago. Has that changed?
