Because I get asked so regularly, I made a deck and screencast with the goal of helping you to understand and to get the best value for AWS pricing.  Here are list of useful tools, when trying to understand AWS pricing:

1) AWS Free Tier information – here
2) AWS Pricing Calculator – here
3) About AWS billing – here
4) RightScale Plan for Cloud cross-cloud pricing calculator – here

Here’s the deck

Here’s the screencast

Feel free to share tips and information that you have for understanding AWS pricing in the comments section of this blog post as well.
