What is a CDN?

CDN is short for content delivery network. A content delivery network (CDN) is a system of distributed servers (network) that deliver pages and other Web content to a user, based on the geographic locations of the user, the origin of the webpage and the content delivery server.

This service is effective in speeding the delivery of content of websites with high traffic and websites that have global reach. The closer the CDN server is to the user geographically, the faster the content will be delivered to the user. CDNs also provide protection from large surges in traffic.

  • Improved security – protect applications and APIs against DDoS attacks.

  • Enhanced performance – accelerate applications, improve mobile delivery

  • Access from anywhere – caches your content across our global network

  • Visitors stay longer – a faster loading website invites users to stay longer

  • SEO Improvement – improves the frequency of web crawlers

  • Lower costs – with less bandwidth use at the source

Technology is constantly changing which means it is important to have a fast-loading website for your visitors. Websites have to deliver more data and content than ever before. And that is where a content delivery network comes into play.

How CDNs Work.

Servers nearest to the website visitor respond to the request. The content delivery network copies the pages of a website to a network of servers that are dispersed at geographically different locations, caching the contents of the page. When a user requests a webpage that is part of a content delivery network, the CDN will redirect the request from the originating site’s server to a server in the CDN that is closest to the user and deliver the cached content. CDNs will also communicate with the originating server to deliver any content that has not been previously cached.

The process of bouncing through CDNs is nearly transparent to the user. The only way a user would know if a CDN has been accessed is if the delivered URL is different than the URL that has been requested.
