Amazon CloudFront is a content delivery network (CDN) that enables you to cache content in Edge
Locations that are located around the world. This brings your media closer to your end users
which reduces latency and improves the user experience.
Amazon EBS Cross Region Replication does not exist (S3 Cross Region Replication does). You can
copy EBS volumes across regions manually (or programmatically), however EBS is not a good way to
get your content closer to your users as you would need to mount the volume to an EC2 instance
(additional cost) and would also need to find a way to keep your files in sync.
Amazon S3 Transfer Acceleration is a feature that is used for accelerating uploads to Amazon S3,
not for downloads.
Amazon Aurora Global Database is designed for globally distributed applications, allowing a
single Amazon Aurora database to span multiple AWS regions. This is a way to have an SQL
database across regions, which is not a good use case for hosting media files.
