Erlang: What They Didn’t Tell You in the Brochure

Erlang is a language designed for building highly concurrent, highly available systems. And, based on our experience using it to build a large-scale VoIP soft-switch, it does a great job of this.

However…every language has a collection of “gotchas” which developers often don’t discover until they’re neck-deep in building a big system. If they’re really lucky, they’ll discover them before the users do.

I love Erlang as a language, but in this respect it’s no different from any others. This talk aims to briefly cover the things it would have been nice to have known before we ran head-long into them such as:

  • How to crash your VM (and how not to)
  • Message queues: they’re not magic
  • Why you can’t just run Erlang as a Unix-style service (and how you can)
  • Hot Code Loading: not as easy as you might hope
  • The OTP: Forget everything they taught you in the first Erlang lesson
  • System monitoring is even more important than you think
