A content delivery network (CDN) is a group of geographically distributed servers that speed up the delivery of web content by bringing it closer to where users are.
CDNs rely on a process called “caching” that temporarily stores copies of files in data centers across the globe, allowing you to access internet content from a server near you. Content delivered from a server closest to you reduces page load times and results in a faster, high-performance web experience. By caching content like web pages, images, and video in servers near your physical location, CDNs allow you to do things like watch a movie, download software, check your bank balance, post on social media, or make purchases without having to wait for content to load.
You could think of a CDN like an ATM. If your money were only available from one bank in town, you’d have to make a time-consuming trip and stand in a long line every time you wanted to withdraw cash. However, with a cash machine on practically every corner, you have fast and easy access to your money any time you need it.
There is no single best CDN (Content Delivery Network) provider — the right choice depends on your specific use case, such as performance needs, geographic reach, security, ease of integration, and cost.
