The AWS Well-Architected Framework contains five distinct pillars used to evaluate and compare your architecture and implementation against AWS best practices. These pillars - Operational Excellence, Security, Reliability, Performance Efficiency and Cost Optimisation - give the guidance to produce stable, efficient and scalable systems.
The AWS Well-Architected Framework includes topics, questions and references to best practises to evaluate the current governance, architecture and implementation. Involving stakeholders and contributors is essential to getting the benefits from using the AWS Well-Architected Framework. However, the most value from using the AWS Well-Architected Framework is often gained by using an experienced and certified AWS Well-Architected partner.
