AWS CloudFront Edge Location

Question

In CloudFront what happens when content is NOT present at an Edge location and a request is made to it?

Answer 1

CloudFront delivers the content directly from the origin server and stores it in the cache of the edge location. This is because CloudFront is a content delivery system, which caches data to the nearest edge location from the user, to reduce latency. If data is not present at an edge location, the first time the data may get transferred from the original server, but from the next time, it will be served from the cached edge.
