Using Alibaba Cloud CDN (Content Delivery Network) is particularly beneficial for optimizing the delivery of content to users across different geographical locations. CDNs are designed to cache static content such as images, videos, stylesheets, and scripts in multiple edge locations around the world. This means that when a user requests content, it can be delivered from the nearest edge location rather than the origin server, reducing latency and improving load times.

By utilizing a CDN, organizations can enhance user experience by ensuring that content is delivered quickly and reliably, regardless of where the user is accessing it from. Additionally, a CDN helps manage traffic spikes and can contribute to better overall site performance and reduced load on the origin server.

In contrast, the other scenarios presented do not align with the primary function of a CDN:

- Hosting complex database systems typically requires services optimized for computation and data management, rather than content delivery.

- Storing backups of on-premises data securely falls under cloud storage solutions rather than CDN functionalities.

- Increasing the processing speed of applications relates more to computational resources than to content delivery, which is the core purpose of a CDN.

Thus, the most appropriate scenario for using Alibaba Cloud CDN is to optimize the delivery of content to users across geographies.
