A content delivery network (CDN) is a distributed network of servers designed to deliver web content quickly and efficiently. Its primary purpose is to reduce latency and improve the loading times of websites and applications by caching content closer to end users. By serving data from the nearest location, CDNs enhance user experience, decrease load on origin servers, and improve website performance during traffic spikes. This technology is essential for businesses that rely on fast and reliable content delivery, especially in ecommerce and media streaming.
