Which component of AWS global infrastructure does Amazon CloudFront use to ensure low-latency delivery?

Amazon CloudFront utilizes AWS edge locations to ensure low-latency delivery. Edge locations are strategically positioned worldwide and serve as content delivery points that cache content closer to end-users. This reduces the physical distance that data must travel, thereby improving access speed and minimizing latency. When a user requests content from CloudFront, the service can deliver that content from the nearest edge location, which results in faster load times for websites, videos, and other resources.

These edge locations play a critical role in accelerating the distribution of dynamic and static web content, as well as APIs, by providing a seamless experience for users, regardless of their geographic location. This setup is particularly beneficial for applications that require high performance and quick response times.

In contrast, AWS Regions and Availability Zones refer to larger geographic areas and their subdivisions that primarily offer compute, storage, and networking resources rather than optimizing content delivery. AWS data centers, while part of the infrastructure, are not specifically designed for low-latency distribution; rather, they function primarily as operational hubs for the resources contained within a region or availability zone.
