What is AWS API Gateway?
Amazon API Gateway is a fully managed service that allows developers to create, publish, maintain, monitor, and secure HTTP, REST, and WebSocket APIs. It acts as a front door for applications to access backend services and functionality.
Why use it in the API Lifecycle?
- API Creation and Management: Allows developers to create, publish, and maintain HTTP, REST, and WebSocket APIs.
- Traffic Management: Handles concurrent API calls, including request throttling, to ensure backend system stability.
- Authorization and Access Control: Secures APIs using AWS IAM, Amazon Cognito, native OIDC/OAuth2 support, and custom Lambda authorizers.
- Performance Optimization: Routes API requests through a global network of edge locations to reduce latency for end users.
- Monitoring: Provides performance metrics, data latency, and error rates through an integrated dashboard with Amazon CloudWatch.
- API Version Management: Enables running multiple versions of the same API simultaneously for iterative development and release.
Best Practices
- Utilize API versioning to iterate, test, and release new API versions.
- Select HTTP APIs for basic proxy functions to manage costs efficiently, reserving REST APIs for scenarios requiring advanced management features.
- Engage with available step-by-step tutorials to understand the service’s functionalities before implementation.
- Regularly monitor API performance, latency, and error metrics through the integrated CloudWatch dashboard.
