In AWS, what is a key feature of a Content Delivery Network (CDN)?

A key feature of a Content Delivery Network (CDN) is that it speeds up the delivery of content globally. CDNs achieve this by utilizing a distributed network of servers strategically located around the world. When users request content, such as images, videos, or web pages, the CDN routes this request to the nearest server in its network. This proximity reduces latency, enhancing the speed and performance of content delivery.

By caching content closer to end-users, CDNs also help reduce bandwidth consumption for the origin server, decrease load times, and provide a more reliable experience, especially during high traffic periods. This makes CDNs particularly beneficial for applications and websites with a global audience, as they ensure that users receive content quickly and efficiently, regardless of their geographic location.

Other choices pertain to storage capacity, compute resource management, and application scaling, which are functionalities related to different AWS services but do not encapsulate the primary role of a CDN within the AWS ecosystem.
