- Number of MySQL servers – 1,800
- Number of MySQL DBAs – 2
- Number of Web servers – 10,000
- Number of Memcached servers – 805
Microsoft Windows Live Platform server architect James Hamilton comments:
The Facebook fleet has grown fairly dramatically of late. For example, Facebook is the largest Memcached installation and the most recent reports I had come across have 200 Memcached servers at facebook. At the Scaling MySQL panel, they report 805 Memcached servers.
The 1,800-to-2 ratio is pretty impressive.
