AWS Well-Architected Tool

Review your architecture and adopt best practices

The AWS Well-Architected Tool is designed to help you review the state of your applications and workloads, and it provides a central place for architectural best practices and guidance. The AWS Well-Architected Tool is based on the AWS Well-Architected Framework, which was developed to help cloud architects build secure, high-performing, resilient, and efficient application infrastructures. The Framework has been used in tens of thousands of workload reviews by AWS solutions architects, and it provides a consistent approach for evaluating your cloud architecture and implementing designs that will scale with your application needs over time.

In addition to the standard guidance provided by the AWS Well-Architected Framework and AWS-developed lenses, the AWS Well-Architected Tool allows you to add specific best practice guidance using custom lenses. By developing your own questions and evaluating your workloads using your organization’s best practices, you can perform reviews based on technology or governance requirements specific to your industry.

To use the AWS Well-Architected Tool, just define your workload, apply one of the AWS Well-Architected lenses or your own custom lens, and begin your review. The tool then provides an action plan to help you build for the cloud using the defined best practices. The AWS Well-Architected Tool is available at no charge in the AWS Management Console.

Step 2: Conduct architectural review

Review your workloads against AWS best practices by answering a set of foundational questions, with the option to create your own custom lens.

Step 3: Apply best practices

The AWS Well-Architected Tool delivers a list of issues found in your workloads and step-by-step guidance to make improvements.

“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 up front.”

Kevin Thorley, Enterprise Architect - Cox Automotive
