AWS Well-Architected Tool
AWS Well-Architected Tool
The AWS Well-Architected Tool (WAT) helps you review and improve your cloud workloads based on the six pillars of the AWS Well-Architected Framework:
Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability.
It guides you through structured questions, identifies potential risks, and provides actionable recommendations to align your architecture with AWS best practices.
How It Works
| Step | Description |
|---|---|
| 1. Define Workload | Create a new workload in the console. Provide details like workload name, description, owner email, environment (e.g., production), region, and account IDs. |
| 2. Apply a Lens | Choose one or more lenses to evaluate your workload — such as: • AWS Well-Architected Framework Lens • Serverless Lens • SaaS Lens • FTR (Foundational Technical Review) Lens • Or even create a Custom Lens. |
| 3. Answer Questions | For each pillar, answer detailed questions about your workload design and operations. Mark what applies, what doesn’t, and justify exceptions if needed. |
| 4. Review Results | After answering, AWS evaluates your workload across the six pillars and highlights High, Medium, and Low Risks. |
| 5. Get Recommendations | The tool generates an Improvement Plan with documentation links, videos, and guidance on how to fix high-risk areas. |
| 6. Save Milestones | Save your review as a milestone (e.g., “Initial Review”) to track improvements over time. |
