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 around the world to cache content closer to users. When a user requests content, CloudFront retrieves it from the nearest edge location, thereby reducing the distance data needs to travel. This minimizes latency, enhances user experience, and speeds up the delivery of content.

While AWS regions represent distinct geographical areas and availability zones are isolated locations within those regions designed for high availability, neither directly focuses on reducing latency for content delivery the way edge locations do. Amazon Virtual Private Cloud (Amazon VPC) is specifically used for networking components and does not pertain to content delivery optimization. Therefore, the key role of edge locations in caching and delivering content makes them essential for low latency in Amazon CloudFront's operation.
