Random flickr things

Web engineer John Allspaw from photo-sharing Web site Flickr gave a seminar at Cal Poly Tuesday that was mostly focused on capacity planning. While most of the technical stuff went over my head, a few interesting/funny moments from the evening:

  • Robocop on a unicorn: Yes, an entire Flickr set. He opened the presentation by showing it to us
  • "They have more servers than God." -About Facebook
  • Normal growth at Flickr in the past year: - 4x increase in photo requests/second - 2.2x increase in uploads/day - 3x increase in database queries
  • The largest average peak is 3,500 photos uploaded per minute
  • Weekly spike in uploads every Sunday night
  • Weekly spike in traffic every Monday morning

Also, I answered a trivia question correctly (How many members does Flickr have? I said 30 million, it was 33 million) so I won a free premium account.
