CloudFront | Notion

Amazon CloudFront is a content delivery web service that integrates with other Amazon Web Services (AWS) products. Developers and businesses can use it to distribute content to end users with low latency (time delay), high data transfer speeds, and no minimum usage commitments.

Content is delivered through a worldwide network of data centers called edge locations. When a user requests data, the request is routed to the edge location that provides the lowest latency.

If content is cached at the edge location, CloudFront delivers it immediately. If it is not cached, CloudFront retrieves the data from an origin that you have defined, such as an Amazon S3 bucket.
