Content Delivery Network
A Content Delivery Network (CDN) is a geographically distributed network of servers that work together to deliver web content and applications to users based on their location. It caches static assets like images, CSS, JavaScript, and videos at edge servers closer to end-users, reducing latency and improving load times. CDNs also provide security features like DDoS protection and SSL/TLS encryption.
Developers should use CDNs when building websites or applications with global audiences to ensure fast, reliable content delivery and reduce server load. They are essential for high-traffic sites, media streaming, e-commerce platforms, and any service where performance and availability are critical. CDNs also help mitigate security threats and handle traffic spikes effectively.
