A Short on the Pinterest Stack for Handling 3+ Million Users

Pinterest co-founder Paul Sciarra shared a bit about their stack on Quora:

  • Python + heavily-modified Django at the application layer
  • Tornado and (very selectively) node.js as web-servers.
  • Memcached and membase / redis for object- and logical-caching, respectively.
  • RabbitMQ as a message queue.
  • Nginx, HAproxy and Varnish for static-delivery and load-balancing.
  • Persistent data storage using MySQL.
  • MrJob on EMR for map-reduce.
  • Git.

Alex Popescu has created a cool diagram of the setup and provided some thoughtful analysis as well.
