On DZone.com there's WordPress instance on an Amazon EC2 instance with the help of Puppet and Joyent appliance, migrating to Linode, and finally, to Amazon with a Bitnami stack, we noticed the common pain of manually configuring each of these environments. Bitnami caused us an even bigger headache by being very difficult to update (apt-get doesn't update the bitnami wrapped AMP stack). We decided to get full control of our box by setting up a stock Debian LAMP stack on AWS using Puppet and git to manage our sites. Here's a gentle introduction on how we did it.

He guides you through the entire process:

• Setting up a micro instance on EC2
• Signing up for unfuddle (for git)
• Installing Puppet (standalone)
• Setting up your git repository to point to unfuddle
• The needed Puppet configuration files to get the WordPress instance deployed

Complete code (and commands) are provided in the post.
