Glossary
Also: Well-Architected review
A question catalogue from AWS for assessing an architecture along six pillars, from operational excellence to sustainability.
The framework is not a certificate but a structured self-interrogation: operations, security, reliability, performance, cost and sustainability. Each pillar comes with questions you can either answer or not.
The value lies less in the answers than in the gaps that surface while going through them, most often around recovery and cost attribution.
