I was also expecting amazing optimization tricks, like: - Designing an MPEG encoder which can take a couple of pictures and render them on the fly, so only saving the pictures, - Carefully spreading the views over a period of time, - Associating the soundtrack at view time, since the soundtrack is the same for everyone, - Using EC2 for the purpose, deleting all vids afterwards, But no, they just used the brute force method. It would be a good job interview question: "How would you serve 700m videos?"
