Background to the article: https://underjord.io/unpacking-elixir-iot-embedded-nerves.ht...
Seems like they deploy Elixir on embedded Linux. The embedded Linux distro is Nerves which replaces systemd and boots to the BEAM VM instead as process 1, putting Elixir as close to the metal as they can.
I know nothing about any of the above (assumption is I'm fool enough to try and simplify) plus I know I've misused the concepts I wrote but that's my point so read the article. All simplifications are salads
