Talk Title: Scaling Facebook - Facebook Tech Talk for Grad Student

s

Talk Abstract: Facebook has grown at an incredible rate in recent ye

ars. In October 2007, Facebook had 50 million active users---distinct user

s who have logged into the website in the past month. 10 months later, the
active user account reached 100 million. An additional 9 months after that
(April 2009), the active user count climbed to 200 million. In July 2010

, Facebook hit 500 million active users.

In this talk, I will discuss
how Facebook''s infrastructure has evolved to scale with such explosive gr

owth from the early days of a single cluster to its current architecture th

at spans across multiple clusters and two coasts. I will explain how our we

b machines interact with memcache and MySQL and highlight the mechanisms we
use to ensure that your data remains consistent within a cluster, across

co-located clusters, and across geographically separated clusters.
