What is this?
API Gateway fronts multiple microservices with path-based routing, auth, and throttling from a single custom domain.
Why should you care?
AwsVerse exposes one api.awsverse.com with routes to Lambda, ECS, and legacy HTTP backends.
See it live — copy this example
Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).
aws apigateway create-resource \
--rest-api-id abc123 \
--parent-id rootid \
--path-part paymentsWhat happened?
- Adds /payments resource to REST API.
- Create method, integration to HTTP VPC Link or Lambda, deploy to prod stage.
Practice next
- Create REST API with custom domain.
- Map /accounts → ECS, /payments → Lambda.
- Enable usage plans per partner API key.
- Migrate hot routes to HTTP API for cost.
- Add request validation models per route.
Remember
Single API edge for microservices. Path routing to diverse backends. Central auth and throttling.
AwsVerse unified API
Mobile app should not know backend topology.
Outcome: API Gateway routes hide three ECS clusters behind one domain.
