It seems django would benefit by brining some of this "in-house", either officially or through blessed third-party tools in the same way that rails does.<p>If deployment and testing is something that everyone has to do in a very similar way should it not be a problem that is solved by the framework the same way that sessions are?
This document is covered with "FAIL" stamps, but they didn't even mention HAProxy as a load balancer! Anyway, I think that slide 135 is what most people do, maybe adding a DB cluster.
