It depends on your configuration. We use the following stack for our environment on Rackspace, but you can configure the same on AWS with EC2 instances.
- Ubuntu 11.04
- Varnish (in memory cache) to avoid disk search
- NginX for static server content
- Apache Dynamic Content for Server (MOD-WSGI)
- Python 2.7.2 with Django
- Jenkins for our continuous assembly
- GIT for version control
- Fabric for deployment.
