Announcing updates to the AWS Well-Architected Framework

We are excited to announce the availability of improved AWS Well-Architected Framework content. In this update, we have made changes across all six pillars of the framework: Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability.

A brief history

The Well-Architected Framework is a collection of best practices that allow customers to evaluate and improve the design, implementation, and operations of their workloads and organizations in the cloud.

In 2012, the first version of the framework was published, leading to the 2015 release of the guidance whitepaper. We added the operational excellence pillar in 2016. The pillar-specific whitepapers and AWS Well-Architected Lenses were released in 2017, and, the following year, the AWS Well-Architected Tool was launched. In 2020, the content for the framework received a major update, more lenses, and API integration with the Well-Architected Tool. The sixth pillar, sustainability, was added in late 2021.

What’s new

Updates to the Well-Architected content include:

Learn, measure, improve, and iterate

Best practices include regularly reviewing your workloads—even those that have not had major changes. We encourage you to assess your existing workloads as your architecture evolves or business needs change, and create milestones for your workloads as they develop. Use the Well-Architected Framework to guide your design and architecture of new workloads, or of workloads that you are planning on moving to the cloud.

Taking best practices into account early in your process can yield high success rates. In effective organizations, each best practice is considered and prioritized with respect to the goal they are trying to achieve.

AWS Well-Architected helps cloud architects build secure, high-performing, resilient, and efficient infrastructure for a variety of applications and workloads. The Framework is built around six pillars—operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability.
