AWS Well-Architected Framework
Learn the 6 pillars of the AWS Well-Architected Framework — the structured approach AWS uses to evaluate and improve cloud architectures.
By the end of this lesson, you will be able to:
- Name all six pillars of the AWS Well-Architected Framework.
- Describe the focus area of each pillar in one sentence.
- Match each pillar to at least one key AWS service or practice.
- Explain the purpose of the AWS Well-Architected Tool.
What Is the Well-Architected Framework?
The AWS Well-Architected Framework is a set of best practices organized into six pillars. It helps cloud architects build secure, high-performing, resilient, and efficient infrastructure. AWS created it so teams have a consistent way to evaluate workloads and identify improvements.
Note
You need to know all six pillars by name and what each one focuses on. You do not need to memorize every best practice within each pillar.
The 6 Pillars
Operational Excellence
Focus
Run and monitor systems to deliver business value, and continually improve supporting processes.
Key practices
- Perform operations as code (infrastructure as code).
- Make frequent, small, reversible changes.
- Learn from operational failures.
Key AWS services
AWS CloudFormation, AWS CodePipeline, Amazon CloudWatch

The AWS Well-Architected Tool
AWS provides a free service called the AWS Well-Architected Tool that lets you review your workloads against the framework's best practices. It asks you a series of questions for each pillar and generates a report with improvement recommendations.
You access it in the AWS Management Console — no installation required.
Tip
The AWS Well-Architected Tool is the service that lets you run a structured review of your architecture against the framework's best practices.
Common Confusions
- Pillars vs. CAF perspectives. The Well-Architected Framework has 6 pillars. The Cloud Adoption Framework has 6 perspectives. They overlap in name (e.g., "Security") but are different frameworks.
- Reliability vs. Security. Reliability = surviving failures and meeting demand. Security = protecting data and systems from threats.
Summary
The AWS Well-Architected Framework is a structured approach to evaluating cloud architectures across six pillars. Know each pillar's name, its one-sentence focus, and at least one associated AWS service. Use the Well-Architected Tool to run a structured review of your own workloads.
