AWS Well-Architected Framework

AWS guidance for designing and operating reliable, secure, efficient, cost-effective and sustainable cloud workloads across six pillars.

Definition

The framework's six pillars are operational excellence, security, reliability, performance efficiency, cost optimization and sustainability (added in 2021). Each pillar includes design principles and best practices, and reviews are conducted with the AWS Well-Architected Tool and specialty lenses.

Example

Before launch, a team runs a Well-Architected review and remediates high-risk issues in the reliability pillar.

Exam tip

Memorize all six pillars; a common trap lists scalability or availability as a pillar, which it is not.
