Although not in Erlang, Discord uses Elixir which runs on the BEAM VM to much success as well for our real time distributed system as well as VOIP signaling components. Looking back years later - it’s safe to say we wouldn’t have chosen anything else.

I'm biased in that I've been heavily involved in the project, but I will stand by the five years of five nines availability claim.

why so many negative votes? Isn't C++ a far more battle-tested language than Erlang? Hasn't C++ a far bigger community than Erlang? To all whose concern is Memory Management, learn about C++11 (and newer standards): smart pointers and heavy use of RAII pattern work shamefully good
I think it is because with Erlang you get Beam and it is the real treasure of the Erlang ecosystem. It not only manifest the philosophy of Erlang well but, more specifically, provides a battle tested run-time for concurrent applications that you cannot get with C++ as you have to (re-)write that concurrent run-time each time.

> It has similar aura than Lisp had before that with Erlang you can do stuff beyond "normal" languages. Like what ?
I think Whatsapp served "at peak" like 450 million users with only 32 engineers.
Do not assume you'll be able to build your own Whatsapp just because of Erlang.
WhatsApp used to use Erlang, not anymore. Facebook rewrote it completely in C++. https://www.quora.com/When-did-Facebook-switch-away-from-usi...
That system was the backend of the functionality currently known as Facebook Messenger, not WhatsApp. One might note, snidely [1], that three-four years after freezing development of an Erlang-based messaging system, starving maintenance work on that system of engineering effort, devoting massive engineering resources to a from-scratch C++ rewrite, and in the meantime blaming the language for relatively minor system…
> Facebook plowed $19B into the acquisition of an Erlang-based messaging system.
They didn't care what it was written in. They would've spent it on Whatsapp even it was written in PHP (like Slack). They paid for users and market penetration.

- telecoms, as it was specifically designed for telecoms.
- "glue" in networked applications: to orchestrate, pass messages around and the like. See GitHub [1] or CoD [2] etc.
In a sense, chats are a mix of both. Erlang is rarely a good fit in pretty much anything else.

Having worked extensively with both Erlang and Elixir in the last 7 years, the main advantage for me has always been the smaller code base that those projects tend to produce when compared to other languages. Especially for projects that have some long-running components to them the Erlang built-in features allow writing really short yet fault resistant systems. The Supervisor system, the per process garbage collecti…
