Implementing dynamic origin modification in Amazon CloudFront – Part 2

This article demonstrates implementing dynamic origin modification in Amazon CloudFront for subscription-based routing using two approaches.

• CloudFront Functions with KeyValueStore for fast query string-based tier routing
• Lambda@Edge with DynamoDB for complex multi-tenant request body routing
• CloudFront Functions ideal for lightweight, low-latency decisions without body access
• Lambda@Edge supports HTTP body parsing and external service integration
• Step-by-step setup includes API Gateway, CloudFront distribution, and code examples
• CloudFront Functions executes at viewer request; Lambda@Edge at origin request
• Includes cURL test examples for basic, standard, and premium tier requests
• Security measures required: authentication, authorization, input validation, encryption

The article provides production-ready patterns for routing requests to different backend instances based on subscription tiers, with detailed configuration and testing guidance.
