The technology that enables the storage and sharing of large files efficiently is called a content delivery network (CDN). CDNs distribute copies of files across multiple geographically dispersed servers, ensuring that users can access content from the nearest server, significantly reducing latency. This enhances the performance of websites and applications that handle large media files, such as video and images. Additionally, CDNs provide benefits like load balancing, improved security, and scalability, making them essential for businesses that require high availability for large file storage and delivery.
