Ask HN: What's the microservice you wish were built/easy to use, but isn't yet?

I have been wondering if there is an application framework to manage microservices. I'm thinking of something that would deal with routing, collection of performance metrics, errors, and monitoring of resource usage. I know Netflix has released software that addresses some of these needs.

Personally I think we need a foundation of reusable microservices that anyone can then build on top of.
