What is the architecture of Facebook?

We use Facebook a lot. At least me. I just come up with an interesting presentation of Director of Engineering of Facebook on its architecture. I am excited to see that they are using LAMP for Facebook. And they empowered their software stack with other open source softwares. They are not using relations in MySQL.
