What is AWS Application Composer?
AWS Application Composer (formerly Infrastructure Composer) helps developers visually design and build serverless applications. You drag and drop resources like Lambda functions, DynamoDB tables, and API Gateways onto a canvas, and it generates the infrastructure code for you.
Key Concepts
1. Visual Canvas
- Drag, group, and connect AWS resources.
- See the architecture diagram as you build it.
2. Generates IaC
- Maintains a deployment-ready infrastructure as code (IaC) definition (typically AWS SAM or CloudFormation) that matches your visual design.
Exam Tips
[!IMPORTANT] "Visually design serverless applications" or "Drag-and-drop infrastructure builder": The answer is AWS Application Composer (or Infrastructure Composer).
Common Use Cases
- Prototyping: Quickly sketching out a serverless app architecture.
- Learning: Understanding how different resources connect (e.g., connecting an SQS queue to a Lambda function).
