Introduction to Amazon EC2Go to Lab
Good basic overview. However, I think it would be helpful to know why the note for "using 'Anywhere', or more specificall, using 0.0.0.0/0 or ::/0 is not a recommended best practice for production workloads." If there is a direction for setting up saying to do that in a lab, people may do it anyway and forget about the note... It may drive home the point more if there were an explanation.
