Posted August 30, 2018

How come CDN speed up the web?

  • CDN’s  characteristics is a system of distributed servers (network- PoP) 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. The closer the CDN server is to the user geographically, the faster the content will be delivered to the user. When the distance from the last user to web server being shorter > shortest distance > least Internet traffic point > reduce latency > accelerate site load times.
  • Instead of connecting directly to web server, users can use cache servers at PoP from the closet of CDN. Because of this points are close to user, so it’s reduces latency, which could be faster couple times to the direct connection method.

How does CDN is increase a website security?
