CDN
A Content Delivery Network (CDN) is a globally distributed network of servers that caches and delivers web content (e.g., images, videos, scripts, stylesheets) from locations closer to end-users, reducing latency and improving load times. It enhances website performance, reliability, and security by offloading traffic from origin servers and mitigating DDoS attacks. CDNs are essential for scaling applications to handle high traffic volumes and global audiences.
Developers should use CDNs when building websites or applications that require fast content delivery, especially for static assets, to improve user experience and SEO rankings. It's crucial for e-commerce, media streaming, and SaaS platforms with international users to reduce latency and handle traffic spikes. CDNs also provide security benefits like SSL/TLS encryption and protection against common web threats.
