I also don't get the comparison to UNIX philosophy into the domain of service development. These are totally different domains with their own patterns of resource usage and interaction. Piping "fairly" simple input -> output code that is sharing machine resources and releasing them at the end of execution is total different than running a micro service architecture across multiple containers/hosts. Even if some of them share the same host there is still extra resource overhead from their allocations that will have a constant baseline.

Unix has a lot of services that listen to 'localhost'. It has had elements of a service oriented architecture since the first daemon was launched, even though the IPC endpoint wasn't always something listening to a socket.
