Yes there is an element of just using encapsulation and single purpose
tool, but there is a lot of trying to do cluster computing well by
keeping the components small and manageable. The downside is the
potential communications complexity.

BTW microservices doesn't mean just Web services/applications per se
(they are a subset), it is any protocol. The Web services/applications
people conveniently forget there are protocols other than HTTP.

"Cloud" is really a destruction of personal computing in favour of re-
centralization of all computing: put the computing power back in the
hands of the people who want to control what you may or may not do with
computers. Beyond this is gets political.

I think you are missing some aspects of why there is sanity to what is
happening, but you are not wrong that there is a lot of "buzz" and
"hype", but that tends to go along with anything "trendy" and "hip".
And there is a lot of reinventing the wheel because the hipsters create
cool new stuff, but have failed to study the last 60 years of computing
before doing so.
