How Are Experienced Web Developers Deploying Django Into Production on EC2?

I have never actually worked for a company which is deploying a Django App (with a large user base), and am curious about what is the best way to do this.

Right now I am hosting a Django App on EC2. The code for the app is sitting in my github account. I have nginx serving static content, and behind it a single apache server running django + mod_wsgi.

I am trying to figure out what the best practice is for "continuous deployment". Right now, after I have added additional functionality I do the following on EC2:

1) git reset HEAD --hard

2) git pull

3) restart apache

4) restart nginx

I have custom logic in my settings.py file so that if I am running on EC2, debug gets set to False, and my databases switch from sqlite3 (development) to mysql (production).

This seems to be working for me now, but I am wondering what is wrong with this process and how could I improve it.

Thanks
