[ec2-beta] ec2 concepts and understanding

[Senthil Palanisami]

The link Jeremy sent out has that information under the section "Preparing
for Bundling":
http://docs.amazonwebservices.com/AWSEC2/latest/GettingStartedGuide/creating-an-image.html#preparing-for-bundling

I strongly recommend reading Amazon's "Getting Started Guide" from top to
bottom - will answer a lot of your conceptual questions. Just substitute the
Ubuntu AMI ID for the getting-started AMI.
