What is CDN or Content delivery network?

(CDN) are the Internet’s transparent backbone in charge of content delivery. Every one of us, whether we realize it or not, interacts with CDNs on a daily basis, whether we are reading articles on news sites, shopping online, watching YouTube videos, or scrolling through social media feeds.

Whatever you do or what type of content you consume, chances are you’ll find CDNs behind every text character, image pixel, and movie frame delivered to your PC and mobile browser.

To understand why CDNs are so popular, you must first recognize the problem they are intended to solve. Latency is the annoying delay that occurs between the time you request a web page and the time its content appears onscreen.
