Lambda@Edge and CloudFront: Modern Edge Computing with AWS

In today's fast-paced digital world, delivering content with ultra-low latency is critical for user engagement. Lambda@Edge allows you to run serverless code globally, bringing computation closer to your users and transforming how you deliver web applications. This text-based course guides you through the fundamentals of edge computing on AWS. You will transition from understanding basic content delivery networks to writing, deploying, and optimizing globally distributed serverless functions that intercept and customize web requests in real time. What you'll learn: First, understand the core concepts of edge computing, content delivery networks, and the AWS global infrastructure. Second, configure CloudFront distributions to trigger serverless functions at different stages of the request-response lifecycle. Third, write and deploy Node.js functions to manipulate headers, perform URL rewrites, and manage dynamic content routing. Fourth, compare Lambda@Edge with CloudFront Functions to choose the right edge compute tool for your use case. Fifth, implement security best practices at the edge, including custom authentication and security headers. Sixth, monitor and debug edge functions using modern observability tools and CloudWatch logs. You will start by mastering foundational edge computing terminology before moving on to practical, step-by-step written tutorials that show you how to write and deploy edge functions. The course concludes with real-world architectural patterns and optimization strategies to ensure your applications run efficiently worldwide. This course is designed for web developers, cloud beginners, and system administrators looking to understand serverless edge computing. No prior experience with AWS Lambda or CloudFront is required, though a basic familiarity with JavaScript and web protocols is helpful. Start reading today to unlock the power of globally distributed serverless applications.
