How Does a CDN Work?
Content Distribution: The CDN copies and distributes your website's static and dynamic content (such as images, CSS, JavaScript, and videos) to multiple servers worldwide.
Caching: Cached copies of your content are stored on the edge servers, reducing the need for repeated requests to the origin server. This minimizes latency and accelerates content delivery.
Load Balancing: CDNs use load-balancing algorithms to distribute user requests across multiple servers, ensuring optimal performance and preventing any single server from becoming overwhelmed.
Security: CDNs often include security features such as DDoS protection, Web Application Firewalls (WAF), and SSL/TLS encryption to enhance the security of your website.
Benefits of Using a CDN:
Improved Loading Speed: By serving content from servers closer to the user, CDNs significantly reduce page load times.
Enhanced User Experience: Faster loading times lead to a better user experience, resulting in lower bounce rates and increased user engagement.
Global Scalability: CDNs enable websites to handle traffic spikes and scale globally without compromising performance.
Reduced Server Load: Caching and load balancing mechanisms decrease the load on the origin server, improving its efficiency and reliability.
In summary, a CDN is a crucial infrastructure for websites and applications seeking to optimize performance, enhance user experience, and ensure seamless global scalability.
