Amazon CloudFront is the content delivery network that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds, all while helping to reduce costs. It achieves its efficiency by storing cached content in multiple edge locations around the world, which allows it to serve content from the nearest geographic location to the user, thereby reducing latency. Amazon S3 is designed for storage and hosting of content but does not by itself distribute content with low latency to users globally. AWS Global Accelerator and AWS Direct Connect are services that optimize internet traffic routing and establish private connectivity to AWS, respectively, but neither fulfills the specific role of a CDN.
