We have released a new version of the Well-Architected Framework. We also added new and updated lenses to the Lens Catalog. Learn more
The AWS Well-Architected Framework Lens and other lenses provided by AWS are updated as new services are introduced, existing best practices for cloud-based systems are refined, and new best practices are added. When a new version of a lens is made available, AWS WA Tool is upgraded to reflect the latest best practices. Any new workloads that are defined use the new version of the lens.
A lens upgrade also occurs when a custom lens that you have applied to a workload or a review template has a new major version published.
A lens upgrade can consist of any combination of:
-
Adding new questions or best practices
-
Removing old questions or practices that are no longer recommended
-
Updating existing questions or best practices
-
Adding or removing pillars
Your answers to existing questions are retained.
Note
You cannot undo a lens upgrade. After a workload has been upgraded to the latest lens version, you cannot go back to the previous version of the lens.
