Content Delivery Network (CDN)

A Content Delivery Network (CDN) is a distributed network of servers and data centers that work together to efficiently deliver digital content to users across the globe. It is designed to improve the performance, reliability, and security of web applications and services by caching and distributing content closer to the end-users. CDNs help reduce latency, minimize bandwidth consumption, and ensure the fast and seamless delivery of digital content, including web pages, images, videos, and other multimedia files. They are commonly used by businesses and organizations to enhance the user experience, reduce costs, and optimize their online presence.
