The following diagram shows an overview of how my website is serviced from AWS

AWS architecture diagram
  1. The viewer requests the website at formarc.net
  2. If the requested object is cached, CloudFront returns the object from its cache to the viewer.
  3. If the object is not in the CloudFront cache, CloudFront requests the object from the origin (an S3 bucket).
  4. S3 returns the object to CloudFront.
  5. CloudFront caches the object.
  6. The objects is returned to the viewer. Subsequent requests for the object that come to the same CloudFront edge location are served from the CloudFront cache.
