What is it?
A system of distributed servers that deliver pages and other web content to a user, based on the geographic locations of the user, the origin of the webpage and the content delivery server.
How does it work?
A Content Delivery Network (CDN) refers to a geographically dispersed network of proxy servers and their respective data centers. Its goal is to provide high availability and performance by distributing the service spatially relative to end-users. CDNs serve a large portion of the internet content today, including web objects (text, graphics, scripts), downloadable objects (media files, software, documents), applications, live streaming media, and social networks.
When is it useful?
In the business context, a CDN is used to quickly deliver web content to users based on their geographical location. When a user requests content from a website, the CDN redirects the request from the originating site’s server to a server in the CDN that is closest to the user and delivers the cached content. This process ensures a faster response and download time of content, providing a better user experience.
Real-World Impact
A prime example of CDN usage is by major online streaming services like Netflix and YouTube. These platforms have a global user base, and the demand for content is massive and simultaneous. By using CDNs, they can store their content in multiple servers spread around the world, enabling faster and efficient content delivery to their users irrespective of their location.
