Content Delivery Network
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 more efficiently. It reduces latency and improves load times by caching content on edge servers closer to end-users, rather than relying solely on a single origin server. CDNs also enhance security and reliability by distributing traffic and mitigating DDoS attacks.
Developers should use a CDN when building websites or applications that serve static or dynamic content to a global audience, as it significantly improves performance and user experience by reducing load times. It is essential for high-traffic sites, e-commerce platforms, and media streaming services to handle spikes in traffic and ensure availability. Additionally, CDNs provide security benefits like SSL/TLS encryption and protection against common web vulnerabilities.
