It’s been over six years since Harvard sophomore Mark Zuckerberg introduced Facebook – run on a single server – initially to Harvard students and eventually to the rest of the world. Since then, the incredible growth of the social network’s infrastructure means it now needs about 60,000 servers to support its 400 million users. And those users are sharing more than six billion pieces of content per week, uploading in excess of 3 billion photos each month and spending 16 billion minutes on Facebook every day.
These astounding figures were quoted by Tom Cook from Facebook's systems engineering group at the O"Reilly Velocity conference last week.
Facebook's servers perform over 50 million operations per second, mainly between the caching tier and web servers. Over a million web sites have included features of Facebook Connect and currently users are viewing in excess of one million photos every second.
To cope with the growth, Facebook has started to build a data center in Prineville, Oregon that will be custom-built to support its server and storage infrastructure.
