Edge Computing Use Cases with Amazon CloudFront

Summary

1. Introduction to Edge Computing with Amazon CloudFront

   • Explanation of the "edge" in the context of AWS Global Edge Infrastructure and Amazon CloudFront
   • Overview of the agenda covering edge compute options, use cases, and best practices

2. Edge Compute Options in Amazon CloudFront

   • Explanation of the hierarchical design of CloudFront with Edge Locations and Regional Edge Caches
   • Introduction to CloudFront Functions and Lambda@Edge as edge compute options
   • Details on the event triggers (viewer request, origin request, origin response, viewer response) and how they can be used

3. Use Cases for Edge Computing

   • Request Preprocessing (e.g., access control, cache key customization, SEO-friendly URLs)
   • Response Rendering (e.g., paywall, A/B testing, session stickiness)
   • Origin Routing (e.g., advanced origin selection)

4. Real-World Edge Computing Use Cases from AppsFire

   • Retrieving enhanced user agent information using CloudFront Functions
   • Collaborating between AWS WAF and CloudFront Functions for efficient origin selection

5. Best Practices for Scaling Edge Computing

   • Understanding and managing the service limits for CloudFront Functions and Lambda@Edge
   • Techniques to optimize function performance (e.g., use of global variables, regular expressions, key-value store access)
   • Strategies to mitigate cold starts for Lambda@Edge functions

The session provided a comprehensive overview of edge computing with Amazon CloudFront, covering the available options, common use cases, and best practices for scaling and optimizing edge computing solutions. The real-world examples from AppsFire demonstrated the practical applications of these technologies and the tangible benefits they can bring to customers.
