Which component of the AWS global infrastructure is specifically designed to cache content closer to end users, thereby reducing latency when services such as Amazon CloudFront are used?
Availability Zone
Edge location
AWS Region
AWS Local Zone
Edge locations are CloudFront points of presence that store cached copies of your content. When a viewer requests an object that is already cached, CloudFront serves it from the nearest edge location rather than from the origin, so the data travels a shorter distance and latency is reduced. Regions and Availability Zones primarily host AWS resources, and Local Zones extend compute services to specific metropolitan areas, but none of these are designed for global content caching.
