Explanation

Amazon CloudFront is the correct choice because:

• Content Delivery Network (CDN): CloudFront is AWS's global content delivery network service that caches content at edge locations worldwide
• Low Latency: By caching content closer to end users at edge locations, CloudFront significantly reduces latency for content delivery
• Global Deployment: With edge locations across the globe, CloudFront is designed specifically for global content distribution

Why not the other options:

• AWS Global Accelerator: Primarily improves availability and performance by routing traffic through AWS's global network, but doesn't cache content at edge locations
• AWS Outposts: Brings AWS infrastructure to on-premises locations, not designed for global content caching
• Amazon Route 53: A DNS service that routes users to endpoints but doesn't cache content or provide edge location caching

CloudFront's primary purpose is to cache and deliver content globally with minimal latency, making it the ideal service for this use case.
