Scaling Facebook To 140 Million Users

Posted by CmdrTaco on from the that's-a-lotta-load dept.

1sockchuck writes "Facebook now has 140 million users, and in recent weeks has been adding 600,000 new users a day. To keep pace with that growth, the Facebook engineering team has been tweaking its use of memcached, and says it can now handle 200,000 UDP requests per second. Facebook has detailed its refinements to memcached, which it hopes will be included in the official memcached repository. For now, their changes have been released to github."

    Myspace used to run on cold fusion but switched to .NET. facebook runs on LAMP, though they have a customized MySQL and a customized linux kernel with support for the hierarchial page pinning algorithm.

    From hardware perspective, Facebook uses 10,000 web servers and 1800 database servers to handle the massive traffic.

    And they also use about 200 memcached servers to speed things up.
