See the Beam/OTP as part of Erlang and now Elixir, Gleam, etc.

Erlang came out of Ericcson when they were building giant telephone switches.

Nowadays things like RabbitMQ and WhatsApp run on the Beam VM.

The beam handles both local and remote nodes, mostly transparently.

Then there are things like Nomad or k8s which try to tackle the problem more like *nix(linux/BSD/etc) does, but across multiple nodes. These are not meant for hard real-time systems like launching rockets obviously, not even for soft real-time.

Even though you can achieve pretty good latency with Erlang because of the lack of global memory (most if not all allocation is local to an Erlang process).
