Is Facebook running one of the world’s biggest Erlang clusters?

Posted by Yariv on May 15, 2008

I just read on the Facebook engineering blog this post describing how Facebook used Erlang to scale Facebook Chat to 70 million active users overnight. WOW.

This announcement should remove any doubts that Erlang is *the* platform for building scalable realtime (aka Comet) applications.

    Very cool, indeed! (Although I’m sure you would have preferred they use Yaws instead of MochiWeb.)

    Where did you read they use MochiWeb?

    I’m actually indifferent to the decision between Yaws and MochiWeb. I started using Yaws because MochiWeb didn’t exist at the time.

    Agreed but with one change — “Erlang is *the* platform for building scalable realtime” …. *messaging* applications. I’m hoping that the application space will increase but I think that heavy data warehousing and gaming have yet to be proven.

    Yariv,

    If you use for example Firebug to look at the HTTP traffic with Facebook Chat you can see that the server header says MochiWeb.

    It’s happening.
