AWS edge locations are used to host the content delivery network (CDN) service Amazon CloudFront, which gives you the ability to cache frequently accessed data closer to end users. This ability can reduce latency in data retrieval times for end users all over the world because the edge locations are often closer to the end users than the region in which the data is hosted.
D. Reducing the load on Amazon EC2 based web servers
AWS edge locations are used to host the content delivery network (CDN) service Amazon CloudFront, which gives you the ability to cache frequently accessed data closer to end users. When data is cached at an edge location and an end user requests data, the request is first routed to the edge location. If the data is found at the edge location, then the data is returned to the end user and the request never reaches the back-end server. This reduces the load on back-end servers because some requests are being offloaded to the edge location.
