How Does AWS CloudFront Work?

The following steps explain how CloudFront delivers the content:

Step 1

The client accesses a website and requests to download a file (like image file).


Client access

Step 2

Now, the DNS routes the client request to the nearest edge location through CloudFront to serve the user request.

Step 3

At edge location, CloudFront looks for its requested cache file. Once the file is found, CloudFront sends the file to the user.
