CDN stands for Content Delivery Network. It is a network of servers located in different geographical locations around the world, which work together to provide fast and efficient delivery of website content, such as images, videos, and other static assets.
When a user requests content from a website, the request is routed to the nearest CDN server to the user’s location, instead of the origin server where the content is hosted. This reduces the distance that the content needs to travel and therefore reduces the time it takes to load the content. Additionally, CDN servers cache content, so subsequent requests for the same content can be served from the local cache, further reducing latency and improving performance.
CDNs are particularly useful for websites with a global audience, as they can help ensure fast and reliable content delivery regardless of where the user is located. They can also help reduce the load on the origin server, since much of the content is being served from the CDN cache instead.

Why should you use CDN?
There are several reasons why you should use a CDN for your website:
Faster content delivery
CDNs reduce the distance that content needs to travel to reach users, resulting in faster loading times and a better user experience.
Improved website performance
Since CDNs can cache content, subsequent requests for the same content can be served from the local cache, reducing the load on the origin server and improving overall website performance.
Better scalability
CDNs are designed to handle high volumes of traffic and can scale up or down as needed, making them ideal for websites with fluctuating traffic levels.
Improved reliability
CDNs have multiple edge nodes located in different regions, which means that even if one node goes down, the content can still be served from another node.
Improved security
Some CDNs offer advanced security features such as HTTPS encryption and DDoS protection to help safeguard your website and content from attacks.
A CDN can help improve website performance, scalability, reliability, and security, resulting in a better user experience and improved website metrics.
