The AWS Well-Architected Tool pulls information together from the official white papers and from AWS documentation to provide a single place where you can catalog the architectural state of your workloads. The recommendations that are given are based on years of experience helping AWS customers to follow best practices while building systems that their customers can depend on.

A Well-Architected review that is all green, with no critical red flags or orange flags for recommended improvements, is the pinnacle of architectural prowess. It's not easy to get there, but with determination and persistence, it's absolutely possible.
