Re: Scaling django (nginx + apache + mod_wsgi + postgresql)

Hi Tom,

you're right, I was not really explicit about what were my lacks of
information. Right now, the following points are the ones I can't found
a howto for the desired deployment:

- Create a master-slave system on postgresql, maintaining all systems up
to date, distributing reads, and centralizing writes
- How to configure a cluster of reverse proxies (a single reverse proxy
can not be enought, and I need to plan to deploy more than 1 load balancers)

The rest (configure apache with mod_wsgit, configure nginx to serve
static content and so on), is now solved on my current deployments, so
it should not be a problem on a distributed environment.

Cheers,

Isaac
