I am a big fan of consolidated and to the point summaries, posters, charts and visual elements for understanding and getting a high-level picture of different technologies. I found following posters quite helpful for getting a high-level picture of the respective technologies and I am sure you will also find them helpful.
Developers are definitely going to appreciate the ones highlighted in yellow.
