Facebook scales to 500 million users

A few of the big numbers Facebook deals with:
* 500 million active users
* 100 billion hits per day
* 50 billion photos
* 2 trillion objects cached, with hundreds of millions of requests per second
* 130TB of logs every day

Remember, there are only three numbers in computer science: 0, 1, and n. This is what scaling horizontally is – break out the infrastructure so that it’s trivial to add another instance of, say, a database server.

    It’s really amazing just how popular Facebook has become over the latter few years, most people had not heard about it a couple of years ago, where as now most people and television programmes are using its technology to communicate.

    Facebook is a great way of communicating with different people, I have made contact with my pen pal from way back in the last few weeks, however we have to be careful just to use it for communication and not for idle gossip.
