# API Gateway

An API Gateway is a server that acts as a single entry point for defined back-end APIs. It handles request routing, composition, and protocol translation.

## Key Concepts

- Request routing
- Rate limiting
- Authentication/authorization
- Request/response transformation
- Circuit breaking

## Common Use Cases

- Microservices entry point
- API versioning
- Rate limiting by client
- Request aggregation
- Protocol translation

## Best Practices

- Implement proper rate limiting
- Use authentication at gateway
- Handle errors gracefully
- Monitor and log requests
- Consider caching
