In general, I found starting with a Erlang/Elixir framework tutorial helps. Phoenix includes a generic wrapper on top of PostgreSQL (Ecto provides data mapping and language integrated query), and hit a surprising number of users per host with trivial code (common game engine back-end.) https://www.phoenixframework.org/ https://www.phoenixframework.org/ https://www.amazon.com/Programming-Phoenix-Productive-Reliable-Fast/dp/1680501453 https://www.amazon.com/Programming-Phoenix-Productive-Reliab... If you don't run away from a framework intro, then dive into the details of the OTP: https://www.amazon.com/Designing-Elixir-Systems-OTP-Self-healing/dp/1680506617 https://www.amazon.com/Designing-Elixir-Systems-OTP-Self-hea... https://www.amazon.com/Elixir-Action-Third-Sa%C5%A1a-Juric/dp/1633438511 https://www.amazon.com/Elixir-Action-Third-Sa%C5%A1a-Juric/d...
