Section titled “Concept”Amazon CloudFront is AWS’s content delivery network (CDN), which quickly delivers content from Edge Locations around the world. The main source of the content is called the origin, such as an S3 bucket, a load balancer or your own web server. The first time someone asks for something, CloudFront fetches it from the origin and caches it at the Edge Location. Later users get that nearby copy, so there’s no need to go back to the origin every time. For security, CloudFront supports HTTPS and works with AWS WAF and AWS Shield.
