What is a cloud storage architecture that manages the data in caches of copied content close to locations of high demand?

A content delivery network (CDN) is specifically designed to optimize the delivery of web content by storing copies of data across a distributed network of servers located geographically closer to end-users. This architecture enhances user experience by reducing latency and improving access speed, particularly for high-demand content such as videos, images, and web pages. When a user requests content, the CDN retrieves it from the nearest cache rather than from a central server, leading to faster load times and less strain on the origin server.

In addition to performance improvements, CDNs provide redundancy and reliability, as they can deliver content even if one server becomes unavailable. This makes them essential for managing high traffic volumes while maintaining the availability of data.

Other storage architectures, such as object-based storage, databases, and file-based storage, serve different primary purposes and are not specifically structured to cache content based on geographical demand in the same way that CDNs do. For example, object storage is focused on handling unstructured data but does not inherently prioritize location-based caching, while databases are designed for data management and retrieval rather than high-demand content distribution. File-based storage primarily organizes files but lacks the location-based optimization features of a CDN.
