Memory hook
AWS Well-Architected Framework = Uses six pillars to evaluate and improve cloud architectures.
Six pillars
- Operational Excellence: observe, automate, and continually improve operations.
- Security: protect identities, infrastructure, and data, with detection and response.
- Reliability: recover from failure, scale dynamically, and meet demand.
- Performance Efficiency: select appropriate resources and evolve with needs.
- Cost Optimization: eliminate unnecessary spend and optimize for value.
- Sustainability: reduce resource waste and environmental impact.
The Framework is the best-practice body; the Well-Architected Tool records reviews, milestones, and improvements. CAF addresses organizational transformation, while Trusted Advisor provides automated account-level checks.
Update: review method and six pillars
- The six pillars are operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability. They form a continuous trade-off framework, not a one-time checklist.
- Define the workload and business outcome, answer lens questions, identify high- and medium-risk issues, and create an improvement plan.
- Game days and production-scale testing validate assumptions under realistic failure and load; reference architecture is not a substitute for validation.
