Since you brought up Sasa Juric, I will second that and also mention their book Elixir in Action. It really helped me get from toy examples to feeling confident running the BEAM in production. This is of course Elixir-centric, but the parts about OTP, inspecting running applications, etc. are really about the BEAM.

Yes, that book is excellent, and I definitely recommend it to anyone new to Elixir. I'd also recommend Joe Armstrong's Erlang book, even if one is eventually wanting to use Elixir.
