The title is somewhat misleading. I clicked expecting to read how someone is managing 2 mln web server instances such nginx or apache. I was curious what kind of company would claim that.

This is Joe's blog, he co-created Erlang 30 years ago. So he's not really affiliated with any company, but rather a voice for Erlang itself.

  It's not a clickbait of course, it's just that the term 'web server' and 'manage' made it easy to misinterpret the subject. Typically, by managing a web server we mean administrative tasks involved in configuring and running a multi-threaded http daemon. Perhaps "2 million web server processes" would have been better.

    Even that would be confusing, as "Erlang process" != "process" for anyone that's not an Erlang programmer(or who doesn't parse "process" as the Erlang variant by default)

As has been said, Joe is known for creating Erlang which is known for running as many processes as the need arises, giving you access to all the cores in a machine as a result.

  Utilizing multiple processor cores was something of an afterthought, IIRC. Initially, the Erlang VM only used a single CPU, and in order to utilize multiple CPUs, one had to start one Erlang VM per CPU/core. One of the nice things about Erlang's general approach is that this was a lot less painful than in many other languages. (I have no idea, though, how much work it was to get the Erlang VM itself to use multiple threads.)

    I always assumed it was one of the main benefits of Erlang since the beginning, back when I tried to attempt to learn Erlang years ago it was one of the main things I learned about it. I've yet to really get down into Erlang since then though.

      FWIW, I think Erlang gained SMP-support at least ten years ago. And running multiple Erlang VMs on one machine - from the Erlang application's perspective - is no different from running them on several machines. The really nice thing about Erlang is that it scales across multiple nodes very smoothly.
