AWS Well-Architected Tool

Review your architecture and adopt best practices

The AWS Well-Architected Tool helps you review the state of your workloads and compares them to the latest AWS architectural best practices. The tool is based on the AWS Well-Architected Framework, developed to help cloud architects build secure, high-performing, resilient, and efficient application infrastructure. This Framework provides a consistent approach for customers and partners to evaluate architectures, has been used in tens of thousands of workload reviews conducted by the AWS solutions architecture team, and provides guidance to help implement designs that scale with application needs over time.

To use this free tool, available in the AWS Management Console, just define your workload and answer a set of questions regarding operational excellence, security, reliability, performance efficiency, and cost optimization. The AWS Well-Architected Tool then provides a plan on how to architect for the cloud using established best practices.

The AWS Well-Architected Tool now offers the ability to mark individual best practices as not applicable during workload reviews. Learn more »

“The Well-Architected Framework has benefited every one of our teams who have implemented it. There were things that people didn't know they could do until we adopted it. We’re thinking about building a lasting effect with Well-Architected and making it something that engineers enjoy using constantly.”

Matt Coulter, Technical Architect - Liberty Mutual



“The Well-Architected Review process helped us see where we were on track and enabled us to check off what worked. But, more importantly, it gave us critical feedback to improve our platform since we’re always looking at how to serve our customers better.

“I definitely recommend using the Well-Architected Review to help improve your current systems. But I also recommend pulling it far into your process. Introduce it to teams earlier. If you leverage it beyond going through it with a team when they’re done, you can use it as the basis to design the application and design a truly efficient architecture upfront.”

Kevin Thorley, Enterprise Architect - Cox Automotive
