The problem with microservices for us has been the composition of operations. Yeah we use the Rx* observable patterns and it helps but the code is still non intuitive for new developers if the language is pretty much procedural/imperative. Even with languages like Scala it still gets confusing. Even if you have a language where threads are cheap (golang) you still have to compose the operations. I have been meaning to see if there are microservice like frameworks for Haskell similar to Hystrix (which is what we use).
