Master CloudFront! CDN fundamentals, caching strategies, and CloudFront vs Global Accelerator in under 40 minutes.
🚀 WHY CDNs MATTER
A user in Tokyo hitting a server in Virginia waits 300-400ms per round trip. A CDN caches content at hundreds of edge locations close to users, dropping latency to milliseconds. CloudFront also provides DDoS protection (Shield + WAF) and reduces origin load.
