AWS API Gateway
AWS managed API gateway service for creating, deploying, and managing REST, HTTP, and WebSocket APIs that front Lambda functions, HTTP backends, or AWS services, with usage plans and throttling.
Best When
You're building serverless applications on AWS and need a fully managed API gateway that integrates natively with Lambda, IAM, and AWS Cognito.
Avoid When
You need multi-cloud portability, complex API transformation policies, or you're not in the AWS ecosystem.
Use Cases
- • Creating serverless API endpoints that invoke Lambda functions from agent workflows
- • Throttling and rate limiting API access for multi-tenant services
- • Managing API keys and usage plans for external developer access
- • WebSocket APIs for real-time agent communication channels
- • Proxying AWS service calls (DynamoDB, S3, SQS) through a REST API
Not For
- • Teams not using AWS ecosystem
- • Complex API transformations requiring custom plugin ecosystems (use Kong or Apigee)
- • On-premises API management
