Amazon API Gateway
Amazon API Gateway publishes REST, HTTP, and WebSocket APIs with managed authorization, validation, throttling, and observability integrations. It provides a controlled front door for synchronous or job-submission GenAI interfaces.
Key points
- Usage plans and throttles protect downstream capacity but are not cost guarantees
- Authorizers and IAM can enforce caller identity
- Integration timeouts bound synchronous backend work
When to use it
- Expose a validated Bedrock chat API
- Accept asynchronous generation jobs and return a status identifier
Exam tips
- Choose API Gateway for managed API contracts and AppSync for graph-oriented client data access
- Do not expose provider credentials, and move work exceeding gateway timeouts to queues or workflows
