Edge Functions for Content Delivery with AWS CloudFront

Modern web applications demand instant load times and dynamic personalization, but routing every request back to a central server introduces latency. Deploying code to the edge solves this by running logic closer to your global users. This text-based course guides you through the fundamentals of edge computing using AWS CloudFront. You will learn to manipulate requests and responses in real-time, implement security policies, and optimize content delivery directly at global edge locations. What you'll learn: - Understand the foundational concepts of content delivery networks (CDNs) and edge computing. - Compare CloudFront Functions and Lambda@Edge to select the right tool for your specific latency and runtime needs. - Modify HTTP headers on the fly to enforce modern security practices like CORS, CSP, and HSTS. - Implement URL redirection, rewriting, and basic A/B testing logic directly at the edge. - Configure cache behaviors and origin request policies to optimize delivery speed. - Practice writing and testing lightweight JavaScript code designed for edge environments. You will start by mastering key terminology and the basic architecture of AWS CloudFront. From there, you will progress to writing, configuring, and deploying edge functions to handle real-world content delivery scenarios. This course is designed for beginner cloud enthusiasts, web developers, and system administrators. No prior experience with AWS or edge computing is required, though a basic understanding of HTTP requests is helpful. Start reading today to bring your application logic closer to your users and supercharge your content delivery.
