A useful Well-Architected review is not a questionnaire exercise. It connects architecture decisions to customer impact, recovery expectations, security risk, operating practices, performance, cost, and sustainability.

01 · Analysis

Define workloads and business criticality

Document service boundaries, owners, data sensitivity, availability expectations, recovery objectives, traffic patterns, and critical dependencies.

02 · Analysis

Collect operational evidence

Prepare architecture diagrams, deployment workflows, IAM patterns, backup evidence, monitoring, incident history, cost allocation, security findings, and runbooks.

03 · Analysis

Review all six pillars

Cover operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability without treating any pillar as isolated.

04 · Analysis

Prioritize findings

Separate urgent risk from medium-term platform improvement, assign owners, estimate effort, define validation, and turn findings into a 30-, 60-, and 90-day roadmap.

Practical checkpoint

Before acting, confirm the owner, evidence, production risk, expected outcome, and validation method for each recommendation.
