My AWS DevOps and SA associate notes – Part 1 – Overview

During the pursuit of these two certifications I jotted down some notes along the way. Sharing is caring, here they are:

Note: These are just notes, items of interest I happened to notice and should 100% not be taken as things that will appear on your exam. Make sure you only use these to run through various things only. Your main resources should be video lessons (acloudguru type stuff), real lab time time (or on the job experience which is always better) and AWS’ own whitepapers, case studies etc..
