What is a content delivery network?

A Content Delivery Network (CDN) is a system of distributed servers located in different geographic locations around the world, that work together to deliver web content, such as text, images, videos, and applications to end-users with high performance and reliability. When a user requests content, the CDN selects the server that is closest to the user’s location to deliver the content, minimizing latency and improving speed. CDNs also provide other benefits, such as increased scalability, reliability, and security, making them an essential part of modern web infrastructure. CDNs are widely used by websites and applications that serve a large number of users and require fast and reliable content delivery.
