The AWS Well-Architected Framework (PDF) is a framework defined by AWS as a series of questions that allow you to understand the pros and cons of the design considerations made while building on AWS.
These questions are built around the five pillars of the AWS Well-Architected Framework which are;
Operational Excellence – The ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures
Security – The ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies.
Reliability – The ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues.
Performance Efficiency – The ability to use computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes and technologies evolve.
Cost Optimization – The ability to run systems to deliver business value at the lowest price point.
“When architecting technology solutions on Amazon Web Services (AWS), if you neglect the five pillars of operational excellence, security, reliability, performance efficiency, and cost optimization, it can become challenging to build a system that delivers on your expectations and requirements. Incorporating these pillars into your architecture helps produce stable and efficient systems. This allows you to focus on the other aspects of design, such as functional requirements.” – The 5 Pillars of the AWS Well-Architected Framework – 15 MAY 2018
