Probably more. I'd say, like, at least 30-40 years.

I mean, the infamous "UNIX way" of "do one thing, do it well" (something we nearly lost with popularity of "do everything in a manner incompatible with how others do it" approach in too many modern systems), when complex behavior was frequently achieved through the modularity of smaller programs communicating through well-defined interfaces.

Heck, microkernels are all about this, and their ideas haven't grew out of nowhere. And HURD (even though it was never finished) is quarter a century old already.

You do know the author is a taking the piss out of the practice, right?

You know nothing in the comment you're replying to indicates I wouldn't, right?

Don't be so quick to assume micros services involve message queuing. For most it seems to just be an elaborate RPC mechanism (unfortunately).

Oh yeah, there's certainly other ways of doing it. My own experience is just that message queuing seems to be the default loosely-coupled RPC mechanism for larger orgs (from before the term 'micro services' was popular).
