CDN
A Content Delivery Network (CDN) is a geographically distributed network of servers that work together to deliver web content, such as images, videos, scripts, and stylesheets, to users based on their location. It caches content at edge servers closer to end-users, reducing latency, improving load times, and enhancing reliability by distributing traffic. CDNs also provide security features like DDoS protection and SSL/TLS encryption.
Developers should use CDN services when building websites or applications that require fast, global content delivery, especially for static assets, media files, or APIs, to improve user experience and handle high traffic loads. It is essential for e-commerce sites, streaming platforms, and SaaS applications where performance and uptime are critical, as it reduces server load and mitigates bottlenecks.
