I think it's akin to the original conception of OOP in Smalltalk, where objects are passed messages. (I've never written ObjectiveC, but I believe that's its paradigm as well.) In that, it's similar to the actor model used in Akka and in Erlang.

If you think of a service as being like a class -- as originally conceived by Smalltalk -- then sending it messages and acting on responses is the very definition of OOP, at least according to Alan Kay, the inventor of Smalltalk and of the term "object oriented programming."

There's an interesting discussion of the definition of OOP here. https://wiki.c2.com/?AlanKaysDefinitionOfObjectOriented

If it were superior for containers, Windows containers wouldn't have withered on the vine.

.NET Core being truly cross-platform is pretty much an official acknowledgement by Microsoft that Windows is not the be-all and end-all. To use their words, they're "meeting developers where they live" instead of insisting that one size fits all, if that size is Windows.

I think more people should post that comment on HN. :)
