Edge locations are the endpoints in aws used for caching content.
In AWS, edge locations are part of the CloudFront content delivery network (CDN) service. These locations are spread across different geographical areas and are designed to cache copies of data closer to end-users, thereby reducing latency and improving the overall performance of web applications and content delivery.
Edge locations serve as endpoints for CloudFront caches, enabling faster delivery of content to end-users by reducing the physical distance that data must travel. They also help to offload traffic from the origin servers by serving cached content directly to users, thereby improving scalability and reliability.
Therefore, in an AWS interview, the correct answer would be:
“Edge locations in AWS refer to the points of presence (PoPs) within the CloudFront CDN network. These locations cache copies of data closer to end-users, reducing latency and improving the performance of web applications and content delivery.”
