• Disqus - Scaling the Worlds Largest Django App. Interesting overview of a commenting system with 75 million comments and 250 million visitors. Lots of good details on how they partition their database, testing, continuous integration, feature switches, caching, delayed signals, and more.
  • Things I learnt tracking a billion events in 24 hours: Know your host, Scaling isn't just servers, My servers need to talk to me more, Kill switches for users, What you don't know is the problem, Don't mix server roles, Know your most important users outside of your site.

    • northscale: wow that is fast! :) RT @cgoldberg: was just running > 100k ops/sec against my 2-node #Membase cluster... zazooom #nosql
    • turbofunctor: The root of many (horizontal) scalability problems is an application level access to a writable filesystem. (Thus, #appengine.)
    • gwenshap: highscalability.com is like Vogue for IT operations. Map-reduce is so last season.
