What is a CDN? (Content Delivery Network)

A CDN, or Content Delivery Network, is a network of servers that work together to deliver website content to users around the world. When you visit a website, the CDN locates the server that is closest to you and sends the website's content from that server, reducing the distance the data has to travel and improving website performance.

CDNs are useful because they help to solve two common problems associated with delivering website content: latency and traffic spikes. Latency refers to the time it takes for data to travel from the server to the user's device. Traffic spikes occur when many users try to access a website at the same time, which can overload the website's servers and cause the website to slow down or even crash.

By distributing website content across a network of servers, CDNs can reduce latency and prevent traffic spikes from affecting website performance. CDNs can also help to improve website security by protecting against DDoS attacks and other security threats.

Overall, CDNs are a powerful tool for improving website performance and user experience, and they are widely used by businesses, organizations, and website owners around the world.
