Lenses

Lenses provide a way for you to consistently measure your architectures against best practices and identify areas for improvement. The AWS Well-Architected Framework Lens is automatically applied when a workload is defined.

A workload can have one or more lenses applied. Each lens has its own set of questions, best practices, notes, and improvement plan.

The following lenses are provided by AWS:

• The Serverless Lens focuses on designing, deploying, and architecting your serverless application workloads in the AWS Cloud. This lens covers scenarios such as RESTful microservices, mobile app backends, stream processing, and web applications. Using this lens helps you apply best practices when building serverless application workloads on AWS.

  For more information, see the Serverless Applications Lens whitepaper.

• The SaaS Lens focuses on designing, deploying, and architecting your software as a service (SaaS) workloads in the AWS Cloud. Using this lens helps you apply best practices when building SaaS workloads on AWS.

  For more information, see the SaaS Lens whitepaper.

For more information about AWS provided lenses, visit AWS Well-Architected Lenses. Note that many AWS lenses exist only as whitepapers and not as lenses in the AWS WA Tool.

You also can create and use your own custom lenses, or use custom lenses that have been shared with you.

Up to 20 lenses can be added to a workload.

If a lens is removed from a workload, the data associated with the lens is retained. The data is restored if you add the lens back to the workload.
