SmugMug Photo Sharing and Video Sharing is a private and long term profitable Premium only commercial web site. Don MacAskill, the CEO of SmugMug, gave the keynote speech at a MySQL conference. Don posted the video of his speech on his blog. He is talking about the Percona builds of MySQL which is what I’m planning to deploy so I was eager to watch his presentation. It is a great summary of the architecture of SmugMug and the problems they are working to solve around MySQL. If you have an interest in web solution architectures you should absolutely check it out.
