This post is not directly about MicroServices. If that is why you are reading it, might as well stop now. Apparently, we are still waiting as for the definition to be finally ratified. The definition, as it stands now, is blurry - Martin Fowler admits. This post is about Actors - the cloud ones - you know. After finishing reading it, I hope I have made it effortlessly clear how Reactive Cloud Actors are the real MicroServices, rather than albeit light RESTful Imperative MicroServices.
