What I would consider one of the most important pieces of this guide is closer to the bottom (https://github.com/open-guides/og-aws#aws-data-transfer-cost...) where it covers cost management strategies. The Data Transfer Costs diagram makes the buried details of AWS networking costs stand out in a digestible way. I've read the AWS docs on this many times and still missed out on some of the nuggets exposed in the diagram.
