As these slides are very old, here's some updates:<p>* We use Flask and nginx in various areas now (the main app is still Django). Our realtime app, for example, is powered off of uwsgi and Flask.<p>* There are nearly 1b monthly uniques across the network serviced by the platform.<p>* ~300 servers<p>* Still Postgres (with Slony, multiple clusters), Redis, Memcache, and some Cassandra for newer things (not comments).<p>Also mostly confident we're still the "largest Django app" in terms of traffic.
What struck me instantly was the use of Slony. I haven't listened to the whole thing yet but I am interested in their justification. Perhaps they just haven't moved to 9.2 yet.
