The primary function of a content distribution network (CDN) is to improve the delivery of digital content to users by utilizing a network of distributed servers. CDNs store cached versions of website content closer to the end-users, reducing latency and load times. This is especially important for media-rich applications such as video streaming or gaming, where fast access is crucial. Additionally, CDNs enhance the availability and redundancy of content, ensuring that even during high traffic periods or outages, users receive a seamless experience, thus improving overall satisfaction and engagement.
