Yep. I’ve gotten first-hand great experiences from it because of the OTP & BEAM:
- An ultra-fast “redirect server” that simply returns 301’s for an old domain. It processes http requests in micro-seconds (a 1/1000th of a millisecond) while using effectively zero CPU and RAM.
- A queue-based SaaS that uses the built-in technology and is rock solid.
So maybe one reason for your shock: you’re stepping into a large “batteries included” framework - not just an http library. So lots of these concepts like Supervisor means wrapping your head around someone else’s design, and figuring out how to plug your ideas in.
I got familiar with Elixir on its own, without the framework overhead, from exercism.org - you do the coding exercises in a test-driven style, on your own computer. I compare my solutions to the highest rated ones. My profile: dogweather's profile on Exercism
