Last month, I went to Brisbane .Net User Group. One of the talks was about Microservice. The key point is we need to make the Microservice right, rather than pretending to have Microservice. I totally agree with that. Because the main key part of Microservice, in my understanding, is self-contained. The microservice won't need to require any external resources and the tasks will be carried out by a microservice is very small. Thus, that is very hard for architects.
