In late 2017, Civitas Learning did an AWS "This is My Architecture" video. It was one of the first. The video walks through how they handled processing personally identifiable information at scale using batch processing.

Now, a few years later, I react to that video and see what's stood the test of time, what could be done simpler given today's technology, and generally critique the design against the AWS Well-Architected Framework in a mini AWS Well-Architected Review.
