I haven't used Elixir/Erlang (though I've read a fair amount about them), but it seems like the BEAM languages would be an ideal model for serverless because processes don't (have to) know which thread, core, or machine they're running on.

When people deploy Elixir/Erlang in production, do they use a single distributed instance or do they run separate instances in their own containers/VMs like you might with something like Node?
