Twitter, an Evolving Architecture

Evan Weaver, lead engineer in the services team at Twitter, recently gave a talk on Twitter’s architecture at QCon London 2009. Abel Avram has a good writeup of the presentation, if you are given to deep strategies about performance (see InfoQ: Twitter, an Evolving Architecture).

The upshot is that Twitter has been converting the architecture away from microblogging architecture — all about creating web pages — to a microstreaming architecture — all about efficiently messaging millions of users when millions of users update their status. Another good theoretical reason to not call it microblogging, by the way.
