A CDN can cache and deliver a wide range of web content, including images, videos, scripts (JavaScript), stylesheets (CSS), HTML pages, and other static files. Some CDNs also optimize the delivery of dynamic content and APIs through intelligent routing and caching strategies.

A CDN stores cached content on servers distributed across various geographic locations. When a user accesses a website, the CDN delivers content from the server closest to the user, reducing the physical distance data must travel. This proximity reduces latency and improves page load times, significantly enhancing website performance.

Yes, CDNs are designed for scalability. They can distribute incoming traffic across multiple servers, allowing them to efficiently handle sudden spikes in traffic or high demand without overwhelming the origin server.

By serving cached content from its own servers, a CDN reduces the number of requests made to the origin server. This offloads traffic and decreases the amount of data transferred from the original hosting infrastructure, resulting in lower bandwidth usage and costs.

CDNs improve page load times, which is a key factor in search engine rankings. Faster-loading websites provide a better user experience and are favored by search engines like Google, helping to improve SEO performance.

CDNs offer built-in DDoS protection by distributing traffic across a vast network of servers. This prevents attackers from overwhelming a single server with traffic. Many CDNs also include security features like traffic filtering and real-time monitoring to detect and mitigate malicious activity.

Yes, CDNs have servers strategically placed around the globe. This global reach ensures that content is delivered quickly and reliably to users no matter where they are located, enhancing accessibility and performance.

Absolutely. CDNs are beneficial for websites of all sizes—from small blogs to high-traffic enterprise platforms. They improve speed, scalability, and security, making them a valuable asset for any website regardless of its scale.

While dynamic content is not as easily cached as static content, modern CDNs use advanced technologies like edge computing, intelligent routing, and request collapsing to optimize the delivery of dynamic content and API responses, improving speed and reliability.

Key factors include the provider’s global server coverage, performance (latency and uptime), security features (like DDoS protection), support for dynamic content, integration ease, analytics capabilities, and pricing structure. It’s important to align the CDN’s features with your specific website needs and goals.
