To deliver images and videos globally with minimal latency in a cost-effective way, which approach should the company use?

Amazon CloudFront is a Content Delivery Network (CDN) service that caches content at edge locations worldwide. This significantly reduces latency by serving content from a location geographically closer to the user. It's also cost-effective as you pay for data transfer out from CloudFront, which can be less expensive than direct S3 transfers for global delivery. Storing content on Amazon S3 with cross-region replication would improve durability and availability across regions but wouldn't inherently reduce latency for global users as it doesn't cache content at edge locations. Implementing a VPN across multiple AWS Regions is for secure network connectivity between private networks, not for public content delivery. AWS PrivateLink provides private connectivity between VPCs and services, not for public internet content delivery.
