A company hosts a static website on Amazon S3 and uses Amazon Route 53 for DNS. As global demand increases, the company must decrease latency for users worldwide in the most cost-effective way. Which solution meets these requirements?

Adding an Amazon CloudFront distribution in front of the S3 bucket is the most cost-effective and common solution for decreasing latency for a static website globally. CloudFront is a Content Delivery Network (CDN) that caches content at edge locations worldwide, serving it closer to users and reducing latency. You would then update Route 53 to point to the CloudFront distribution's domain name. Replicating S3 buckets to all regions is expensive and complex for a static website, as S3 is not designed for global content distribution in this manner. AWS Global Accelerator is effective for improving performance for applications that require consistent, low-latency access, but for static content, CloudFront is generally more cost-effective and optimized. S3 Transfer Acceleration speeds up uploads to S3, not content delivery to end-users, so it doesn't address the latency issue for website visitors.
