1.Content Delivery Network (CDN): Amazon CloudFront is a CDN that accelerates the delivery of content by caching it at edge locations that are closer to the end-users1.

1.Edge Locations: These are data centers located around the world that store cached copies of content so that it can be delivered more quickly to users1.

1.Low Latency: When a user requests content, DNS routes the request to the CloudFront Point of Presence (POP) that can best serve the request, typically the nearest CloudFront POP in terms of latency1.

1.Cache Check: CloudFront checks its cache for the requested object. If the object is in the cache, CloudFront returns it to the user1.

1.Cache Miss: If the object is not in the cache, CloudFront forwards the request to the origin server for the object, and then the origin server sends the object back to the edge location. As soon as the first byte arrives from the origin, CloudFront begins to forward the object to the user and adds it to the cache for the next time someone requests it1.
