Answer: Edge locations

Amazon CloudFront is AWS's Content Delivery Network (CDN) service that uses **edge locations** to cache and deliver content to end users with low latency. **Key points:** - **Edge locations** are data centers located in major cities around the world that cache content closer to end users - When users request content, CloudFront serves it from the nearest edge location, reducing latency - **AWS Regions** are geographic areas containing multiple Availability Zones for primary infrastructure - **Availability Zones** are isolated locations within Regions for high availability - **AWS Direct Connect** is for dedicated network connections between on-premises and AWS Edge locations are specifically designed for content delivery and are the backbone of CloudFront's low-latency performance.
