How Does AWS CloudFront Work?
The following steps explain how CloudFront delivers the content:
The client accesses a website and requests to download a file (like image file).
Now, the DNS routes the client request to the nearest edge location through CloudFront to serve the user request.
Serve user request
At edge location, CloudFront looks for its requested cache file. Once the file is found, CloudFront sends the file to the user.

But, if the file is not found then CloudFront compares the requirements with the specifications and shares it with the respective server.
Web server - CloudFront
The web server responds to the request by sending the files back to the CloudFront edge location.
As soon CloudFront receives the file, it shares it with the client and adds the file to the edge location.
