Continuous Deployment is the natural progression of Continuous Integration. This site (a4word.com) provides a simple example whereby after each commit to the database, a suite of tests are run, the application is converted to static html (but maintain the .php extension so internal links work as expected), and the result is deployed to S3.
The script CD portion of the script, simply 'updates' the git repository on the remote server
#!/bin/bash
echo 'About to update a4word.com'
ssh deployer@a4word.com 'cd /home/deployer/apps/portfolio; git pull --rebase'
echo 'Done!'
On each push, the message would look similar to:
$ git push
