I think an important thing to keep in mind when discussing monoliths or Microservices is that you can build modular code without needing multiple binaries, processes, or server instances. If you follow best practices when creating a monolith, creating well-defined modules with clear input and output boundaries, then it should be relatively easy to split those modules into separate programs and create ways for those modules to communicate, if it later becomes necessary to move towards a micro-services architecture.
