Content Delivery Networks for Web Performance and Security

Slow loading times can drive users away from your website in seconds. To deliver fast, reliable, and secure experiences globally, modern web developers and systems engineers rely on content delivery networks. This course explains how content delivery networks function behind the scenes to optimize asset delivery and protect web infrastructure. You will transition from understanding basic web hosting to designing efficient global caching strategies. By learning how content delivery networks route traffic, cache files, and mitigate security threats, you will gain the skills to optimize any web application for speed and reliability. What you'll learn: - Understand core networking concepts, caching terminology, and how content delivery networks function - Configure caching rules, time-to-live settings, and cache-control headers for optimal asset delivery - Implement modern security measures including DDoS protection, web application firewalls, and SSL/TLS termination - Analyze origin server offload, cache hit ratios, and latency metrics to measure performance gains - Apply modern edge computing concepts to run lightweight scripts closer to your global users The course begins with foundational concepts, explaining how domain name systems and global routing work together to direct traffic. You will then progress through caching strategies, security configurations, and advanced features like edge computing and dynamic content acceleration. This course is designed for web developers, system administrators, and technology enthusiasts who want to improve web performance. No prior networking experience is required to get started.
