Appendix A: Relation to AWS Well-Architected

AWS Well-Architected helps cloud architects build secure, high-performing, resilient, and efficient infrastructure for their applications and workloads. Based on five pillars — operational excellence, security, reliability, performance efficiency, and 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 best practices for organizing your AWS environment addressed in this guide augment and support the best practices represented in the following sections of the Well-Architected pillars.

  • Organization - Operating Model – Use of multiple AWS accounts and OUs enable you to support multiple operating models within a common overall AWS environment.

  • Prepare – Mitigate Deployment Risks – Use of separate AWS accounts for deployment-oriented operations help secure those operations and isolate them from the targeted test and production workload environments.
