The AWS Well-Architected Framework provides guidance to help organizations design and operate reliable, secure, and efficient infrastructure on AWS. It was first introduced in 2015 and has continued to evolve with new best practices. The framework consists of five pillars - operational excellence, security, reliability, performance efficiency, and cost optimization. It includes a self-assessment tool that allows users to evaluate their workloads against the best practices and identify areas for improvement. The tool uses a PDCA (plan-do-check-act) approach to continuously monitor and make adjustments to infrastructure.
