What is the primary purpose of Sitecore's Content Delivery Network (CDN)?

The primary purpose of Sitecore's Content Delivery Network (CDN) is to optimize content delivery speed and performance. A CDN functions by distributing content across multiple geographical locations, which allows users to access data from a server that is physically closer to them. This reduces latency, leading to faster load times and a smoother user experience. Additionally, CDNs can handle large volumes of user requests, enhancing the scalability and reliability of the content delivery process.

While managing user access rights, creating backups of media items, and defining the layout of Sitecore pages are all important aspects of Sitecore's functionality, they do not pertain to the specific role of a CDN. In contrast, the CDN is explicitly designed to improve how quickly users can retrieve content, ensuring that they receive data efficiently no matter their location. This is vital for performance-driven applications in today's digital landscape.
