Content Delivery Network (CDN)

What is a Content Delivery Network?

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. Data centers across the globe use caching, a process that temporarily stores copies of files, so that you don’t have to wait for a file to download from the server where it originated. A CDN also uses compression, which reduces the size of files before they’re transferred, making them quicker to deliver.
