What is a CDN?

A Content Delivery Network (CDN) is a system of distributed servers that work together to efficiently deliver web content to users based on their geographic location. CDNs are used to
improve the performance and availability of websites and applications by caching and distributing content such as images, videos, and other static files to servers that are closer to the end users.

When a user requests a web page, the CDN will redirect the request to the nearest server, rather than having it sent all the way back to the origin server. This reduces the distance that the data has to travel, which in turn reduces the amount of time it takes for the page to load.

CDNs also help to reduce the load on the origin server by caching and serving content from a network of edge servers. This can help to improve the scalability and availability of a website, as well as protect it from traffic spikes and DDoS attacks.

Another benefit of CDN is that it can improve the security of a website by using features such as SSL offloading, DDoS protection and Web
Application Firewall.

Benefits of a CDN

Improved Content Availability and Redundancy - A CDN can handle high-volume traffic and withstand hardware failure which can cause downtime for your website.

Increased Website Security - A CDN can increase security by preventing vulnerability attacks, stopping brute force attempts and mitigating DDoS attacks.

Improved Website Load Times - A CDN helps visitors to experience a faster loading page and distribute content closer to website visitors.

Reduced Bandwidth Costs - A CDN can reduce bandwidth consumption costs through caching and optimization and increase content availability.
