AWS Well-Architected Tool, also known as AWS WA Tool, is a service in the cloud that provides a steady process for managing architecture using AWS best practices. In simple words, it helps in documenting and suggests improvements required for the architecture.
In this guide, I’ll walk you through a complete step-by-step guide of using the AWS Well-Architected Tool. It involves creating a workload, reviewing the Reliability Pillar questions, saving the workload, taking a milestone, and examining and downloading the Well-Architected Review report.
New to the Amazon Web Services? Here are the simple steps to Get Started with AWS!
Before that, I would like to give a short note on AWS Well-Architected Framework. The AWS Well-Architected Framework documents a set of foundational questions that helps you understand how a specific architecture aligns with cloud best practices.
Understanding terms that we use in AWS WA tool and AWS WA Framework
- Workload identifies a set of components that deliver business value. They can be either simple or complex websites
- Milestones mark key changes in your architecture
- Lenses provide a way for you to standardly measure your architectures against best practices and help to identify areas for improvement.
Getting Started with AWS Well-Architected Tool
The main sections under the WA tool are:
- Creating an IAM User role
- Define the Workload
- Document the Workload
- Review the improvement plan
- Make the improvements and measure the progress
1. Creating an IAM User role
- Create an IAM user or use an existing one linked with your AWS account.
- Grant the IAM user access to AWS Well-Architected Tool.
- Apply the WellArchitectedConsoleFullAccess managed policy to the user for full access.
- Apply the WellArchitectedConsoleReadOnlyAccess managed policy to the user for read-only access.
2. Defining Workload
- Sign in to the AWS Management Console using the following URL https://console.aws.amazon.com/wellarchitected/
- Choose Define workload under Define a workload section.
- Feed the following fields as
Name -> Website which you are working for
Description ->enter a description of the workload.
Environment -> production environment.
- Choose any AWS Regions in which your workload runs and type Non-AWS regions as any region outside of AWS
- Leave the rest of the fields empty since it’s optional and click on the Next button.
- Under Apply Lenses, we prefer AWS well-architected framework.
- Next, click on Define Workload and then Start reviewing to review your workload.
- Click AWS Well-Architected Framework under Start reviewing to proceed with documenting the workload.
3. Document the workload
- To document workload state, you should answer the questions under categories termed as pillars for the following: operational excellence, security, reliability, performance efficiency, and cost optimization.
- Choose the best practices to be followed for each question.
- Enable Question does not apply to this workload if it doesn’t suit for your workload
- Click Next to proceed with the next set of questions.
- You can pause this process any time by clicking Save and exit and resume by selecting the name of the workload under Workloads in the left navigation pane.
- Hit Continue reviewing and start answering the questions where you left off.
- An overview page for the workload appears, once all the questions were answered.
- Click Save Milestone for the created workload.
- Feed the Milestone name as Version 1.0 and hit Save.
Note: Milestone names must be unique within a workload.
- To generate a workload report, click on the Generate report. A PDF file will be created representing the state of the workload, the number of risks identified, and a list of suggested improvements.

4. Review the improvement plan
- To review the improvement plan, choose AWS Well-Architected Framework from the Lenses section of the Overview page.
- Then click on the Improvement plan.
Here I got eighteen high-risk items and one medium risk item which were identified by the AWS Well-Architected Framework Lens.
5. Make the Improvements and measure the progress
- After making changes, you can return to the Improvement plan and see the effect those changes had on the workload.
- Save the milestone at this point and check on the status of workload by clicking the Milestones tab
- Click on the Dashboard located left navigation pane to see the completed workloads and milestones of well architected framework.
