Simply, the AWS Well-Architected Framework helps you understand the pros and cons of decisions you make while building systems on AWS. It is a set of best practices for building secure, high-performance, resilient and efficient infrastructure. These best practices are a distillation of years of observation of cloud based projects. There are 5 pillars of the AWS Well-Architected Framework. Operational excellence, security, reliability, performance excellence, and cost optimization. There are… Read More »What is the AWS Well-Architected Framework?
