CDN
A Content Delivery Network (CDN) is a geographically distributed network of servers that work together to deliver web content and applications to users more efficiently by caching content at edge locations closer to end-users. It reduces latency, improves load times, and enhances reliability by distributing traffic across multiple servers, often handling static assets like images, CSS, JavaScript, and videos. CDNs also provide security benefits such as DDoS protection and SSL/TLS encryption.
Developers should learn CDN concepts to optimize website and application performance, especially for global audiences, by minimizing latency and bandwidth costs. Use cases include serving static content for high-traffic websites, streaming media, accelerating API responses, and improving security for web applications. It's essential for scalability in e-commerce, media distribution, and any service requiring fast, reliable content delivery.
