This example demonstrates how to implement an API Gateway using HTTP Server to manage routing, authentication, and request handling.

Key Components

  • Routing Logic: Directs incoming requests to appropriate backend services.
  • Authentication Middleware: Validates API keys or tokens (e.g., Bearer_Token).
  • Caching Layer: Improves performance with Redis_Cache integration.

Steps to Implement

  1. Set Up Reverse Proxy
    Configure the gateway to forward requests to backend services based on path or headers.

  2. Add Rate Limiting
    Use Token_Bucket algorithm to control request frequency.

  3. Integrate Monitoring
    Log request metrics to Prometheus_Dashboard for real-time analysis.

Best Practices

  • Always validate input data to avoid Security_Vulnerabilities
  • Use HTTPS_Encryption for secure communication
  • Test with Postman_Tool for API validation
