A content delivery network (CDN) is a distributed network of servers that are used to deliver content to users over the internet. The primary purpose of a CDN is to improve the performance and availability of websites and other online content by reducing the distance that data has to travel and by distributing the load across multiple servers.
CDNs are used to deliver a variety of content, including web pages, videos, images, and other static or dynamic content. They work by caching copies of the content on servers that are located in strategic locations around the world, and then delivering the content to users from the server that is closest to them. This helps to reduce the time it takes for the content to reach the user, and it can also improve the overall performance and scalability of the content delivery system.
CDNs use a variety of techniques to optimize content delivery, including load balancing, caching, and compression. They can also provide additional features such as security, analytics, and traffic management. CDNs are widely used by a variety of organizations, including businesses, media companies, and government agencies, to deliver content to users around the world.
