Found this super-interesting article at one of my favorite websites, Data Center Knowledge: Facebook Now Has 30,000 Servers
Some of the interesting points are:
- 30,000 servers
- Added 20,000 servers in 18 months
- Stores 80 billion images (20 billion but 4 sizes per image)
- 600,000 photos served per second
- 25TB log data generated daily
- 230 engineers
You can view the CNS 2009 Lecture series webcast where Jeff Rothschild (facebook.com/jeff of course), VP of Technology @ Facebook, presented this information and some more tidbits at the post High Scalability: High performance at massive levels – lessons learned at Facebook discussing this presentation.
I’m glad I only have 400 servers.
