Understanding Content Delivery Networks (CDN): A Comprehensive Guide
A Content Delivery Network, or CDN, is a geographically distributed group of servers that work together to provide fast delivery of Internet content. At its core, a CDN's primary goal is to improve website performance and reliability by bringing content closer to users. This means that when you access a website or application, the data, such as images, videos, and code, is served to you from a server that is physically nearer to your location, resulting in quicker loading times and a smoother online experience.
