A Well-Architected Framework

AWS Well-Architected helps cloud architects build secure, high-performing, resilient, and efficient infrastructure for their applications and workloads.

Based on five pillars:

1. operational excellence

2. security

3. reliability

4. performance efficiency

5. cost optimization

AWS Well-Architected provides a consistent approach for customers and partners to evaluate architectures, and implement designs that can scale over time.

The AWS Well-Architected Framework started as a single whitepaper but has expanded to include domain-specific lenses, hands-on labs, and the AWS Well-Architected Tool. The AWS WA Tool, available at no cost in the AWS Management Console, provides a mechanism for regularly evaluating your workloads, identifying high risk issues, and recording your improvements.

AWS has an ecosystem of hundreds of members of the Well-Architected Partner Program. Engage a partner in your area to help you analyze and review your applications.
