AWS Application Composer
AWS Application Composer was renamed AWS Infrastructure Composer on October 4, 2024; it is a visual builder within Amazon Web Services, originally scoped to serverless applications, now used to visually design and build architectures from any AWS CloudFormation resource.
Key points
- Lets developers visually design and build applications by arranging and connecting AWS resources, dragging and dropping to compose an architecture rather than hand-writing a template.
- Originally launched (at re:Invent 2022) scoped to serverless application design; AWS expanded it to support any CloudFormation resource, which is why it was renamed from “Application Composer” to “Infrastructure Composer” to reflect that broader scope.
- Complements services such as AWS Lambda, Amazon API Gateway, and AWS Step Functions when composing serverless architectures, and integrates with the CloudFormation console as a way to build templates visually.
