Data Centers (cloud(y))

A content delivery network, or CDN, is a distributed network of servers that are designed to deliver content, such as websites, applications, and videos, to users more efficiently. CDNs are commonly used to improve the performance and availability of online content by reducing the distance that data has to travel between the server and the user.

CDNs typically consist of a large number of servers that are strategically placed in locations around the world. When a user accesses content that is hosted on a CDN, the request is routed to the server that is closest to the user, which can reduce the amount of time that it takes to transfer the data.

CDNs are often used by large websites and online services that receive a lot of traffic, as they can help to improve the user experience by reducing the time it takes for pages to load and by making content more available. CDNs can also help to reduce the load on a website's own servers, which can improve its overall performance and reliability.

Overall, CDNs are an important tool for improving the performance and availability of online content, and they are used by many of the world's largest and most popular websites.
