Programmers have always partitioned their code in, roughly, the following way:

   - lines
   - functions
   - objects
   - modules
   - binaries

The languages/terms differed, but that's how software has been constructed since approximately forever, and we've always had debates on optimal size/length of lines/functions/objects/modules, etc. We've also had numerous reincarnations of binaries talking to each other over some form of RPC. What happened here was a marketing knife-war between companies in the container management space. Then someone (we'll never remember who) tried to differentiate by coining this term, which basically means "binaries with RPC".

Every binary in your /usr/bin/ is a microservice. Just type `watch date` and enjoy two microservices running, no need for containers/kubernetes :)
