I like how they took a simple use case and were able to show the key concepts of designing stuff with HA as a priority. I'd have like to see some hints about security too, that would have been a nice addition

Thanks! Actually we published a course on AWS Security a few days ago: https://cloudacademy.com/amazon-web-services/courses/introdu...

Good starting point. I think it would be great (perhaps PPallemberg agrees) to have some advanced stuff as well - that's the hardest to understand well.
