A few questions arose about how to use the Drupal Amazon EC2 AMI we released in August
. We added some screenshots to the page to help show how to configure it and clarified the instructions a bit. To help further, I created a quick screencast demonstrating the process of launching the AMI, connecting it to persistent storage, and then stopping the instance and reconnecting the persistent storage to another instance.
Popping this out to full screen will let you see the details.
