The correct choice for reducing load times for global users is a content delivery network. Specifically, Amazon CloudFront is designed to deliver content with high bandwidth and low latency by caching copies of the site's assets at network edge locations closest to the user. CloudFront effectively minimizes the physical distance the data travels, thereby speeding up the delivery of content. While other services like Wavelength Zones and Local Zones bring AWS services closer to end users for particular use cases and are not designed for content delivery, AWS Regions and Multi-AZ are primarily for hosting and improving the availability and redundancy of applications, not for global content distribution.
