Facebook infrastructure up to 10,000 web servers

April 23rd, 2008

By Justin Smith

Rich Miller points out some notes from a recent MySQL user conference during which Facebook VP of Technology Jeff Rothschild gave some stats on Facebook’s server infrastructure:

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.

Now the question is… how many physical boxes?

Sounds good; but it’s not how many instances, but how many tables, models, columns.
my guess is that they’ve kept it pretty simple and can easily use automation to scale out across that number of instances.

My guess is that once you have a good replication scheme it’s all about replacing failing hardware and not so much about actually doing the DBA work.
