Why toppcloud will not be agnostic. Ian Bicking’s toppcloud aims to offer deployment with the ease of use of AppEngine against a standard, open source Ubuntu + Python 2.6 + mod_wsgi + Varnish stack. Here he explains why he’s not going to vary the required components: keeping everything completely standardised means everyone gets the same bugs (and the same fixes).

Fabric, Django, Git, Apache, mod_wsgi, virtualenv and pip deployment. I’m slowly working my way through this stack at the moment—next stop, fabric.

Scaling Django web apps on Apache. Cool to see this kind of article cropping up on IBM developerWorks, but it’s a shame they don’t mention mod_wsgi.

How to use Django with Apache and mod_wsgi. My favourite deployment option is now included in the official Django docs, thanks to Alex Gaynor. I tend to run a stripped down Apache with mod_wsgi behind an nginx proxy, and have nginx serve static files directly. This avoids the need for a completely separate media server (although a separate media domain is still a good idea for better client-side performance).

Future roadmap for mod_wsgi. mod_wsgi 3.0 isn’t too far off, and will include Python 3.0 support, WSGI application preloading and internal web server redirection (similar to nginx X-Accel-Redirect). Version 4.0 plans a major architectural change that will allow multiple versions of Python to be run from the same Apache.

Load spikes and excessive memory usage in mod_python. “The final answer? Stop using mod_python, use mod_wsgi and run it with daemon mode instead. You will save yourself a lot of headaches by doing so.”

The Django and Ubuntu Intrepid Almanac. Will Larson’s impressively comprehensive guide to configuring and securing an Ubuntu VPS from scratch to run Django, using PostgreSQL and Apache/mod_wsgi behind nginx.

modswgi: Debugging Techniques. mod_wsgi is excellent software, and the documentation is equally superb. I used these instructions recently to run the Python debugger inside a running instance of Apache, which helped my track down some import errors that weren’t occurring with Django’s development server.

Setup mod_wsgi for Django and Shared Hosting. Tutorial by David Cramer; attached are useful comments from mod_wsgi author Graham Dumpleton.

Version 2.0 of mod_wsgi is now available. Includes features that should make Python (and Django) on shared hosting much easier: a non-root user can touch their WSGI script file to restart just their application’s daemon processes when they make changes and Python virtual environments are supported to allow different versions of packages without interference.

mod_wsgi 1.0 Release Candiate Available. mod_wsgi is shaping up to be an excellent alternative to mod_python.
