AWSnap! Snappy Ubuntu Now Available on AWS!

Awww snap!

That's right!  Snappy Ubuntu images are now on AWS, for your EC2 computing pleasure.

Enjoy this screencast as we start a Snappy Ubuntu instance in AWS, and install the xkcd-webserver package.


And a transcript of the commands follows below.
