not automatically but its pretty easy to configure in your supervision tree file. I don't know the details because whatever happens by default has taken care of our needs so far.
IT does automatically distribute processes across all the cores on a cpu though.
What I like about the Erlang platform is that it seems like it has the most sensible “microservice” story: deploy your language runtime to all the nodes of a cluster and then configure distribution in code. Lambdas, containers, etc. all push this stuff outside your code into deployment tooling that is, inevitably, less pleasant to manage than your codebase.
