Which aspect of the AWS environment will support this requirement?

Explanations:

Availability Zones are isolated locations within a Region, but they do not represent geographic locations outside the Region. They provide redundancy and fault tolerance within a Region, not direct proximity to global users.

Edge locations are primarily used for Amazon CloudFront and other content delivery services. They serve cached content closer to users but are not suitable for running EC2 instances.

AWS Regions are large geographic areas that contain multiple Availability Zones. Running EC2 instances in Regions closest to global users ensures low latency and improved performance.

Regional edge caches are part of CloudFront’s infrastructure, designed to optimize content delivery, but they do not host EC2 instances or provide compute services.
