How fast Using or Not Using CDN Speed on AWS is?

I had the opportunity to use a CDN (Contents Delivery Network) for a project and tested how much faster it would be with CloudFront.

• Comparison

  • common specs
    • instance type
      AWS EC2 t2 micro
    • OS
      Amazon Linux
    • Region
      Tokyo
  • different specs
    • without CDN
      • All contents are provided by the same server.
    • with CDN
      • Movie, Image, and Audio files are provided by CDN.
      • CDN is working from AWS S3 and AWS CloudFront.

• Test Server
  I used GTmetrix (https://gtmetrix.com/) to measure each loading time. This site has very usefull following funcitons.

  • Test server location is changeable.
  • Data are be comparable.

• Result
  
  If you’re going to create a web service to deliver contents, you should at least use a CDN.
