Right off the bat, Newman advises that we should «think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development». These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as process and organization.
