AWS API Gateway - Summary

AWS API Gateway is a fully managed service that allows you to create, publish, maintain, monitor, and secure APIs at any scale. It's commonly used to build and expose RESTful APIs and WebSocket APIs that act as the front door for applications to access data, business logic, or functionality from your backend services like AWS Lambda, Amazon EC2, or other AWS services. Here's an overview of how AWS API Gateway works:

Key Components and Workflow of AWS API Gateway:

1. API Creation and Configuration:
2. Integration with Backends:
3. Request Handling and Mapping:
4. Security and Throttling:
5. Response Transformation:
6. Deployment and Staging:
7. Monitoring and Logging:
8. Caching:

Use Cases:

• Microservices Communication: Acts as a gateway for microservices, centralizing API management.
• Serverless Applications: Easily integrates with AWS Lambda to create serverless applications.
• Rate Limiting and Throttling: Helps to protect backend systems by controlling API traffic.
• API Versioning and Lifecycle Management: Supports versioning and lifecycle management of APIs through stages and deployments.

AWS API Gateway simplifies the process of creating and managing APIs, providing built-in features for scalability, security, and monitoring, which can greatly accelerate the development of APIs and microservices architectures.
