In late 2016, Lyft did an AWS "This is My Architecture" video. It was one of the first. In the video they explained how they tackled the problem of discovering what microservices were available and healthy in their environment.

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.
