Thanks nderground for sharing your experiences and your Java ecosytem code for AWS!

On your point regarding the development of web applications, I would argue studying for AWS certification is not primarily about passing the exams, but also about what we learn leading up to the exam. There’s two critical points to the development process: designing a good architecture, and writing code to implement this. I think the certifications play a strong part in one’s success for the former, before going on to write the code.

On the running joke about test-driven development, I think it’s good AWS encouraged this approach. I would encourage others reading this to do the same, and maintain strong test coverage for all their AWS code.
