Scaling fast-growing Facebook

In this video interview, Jonathan Heiliger, vice president of technical operations at Facebook, talks with about managing Facebook's hypergrowth. Heiliger is a rock star infrastructure geek. He was the CTO of Global Crossing at age 23, worked at Marc Andreessen's Loudcloud and spent time as the head of Web engineering at Walmart.com.

During the interview, Heiliger said that Facebook has more than 10,000 servers and leverages mostly open-source software across a distributed architecture, with thousands of MySQL instances. "It's almost a new challenge every day," Heiliger said regarding the challenges of keeping up with the growth in users--about 250,000 new users per day. He said that Facebook is considering building its own data centers, but for now is renting.
