A CDN is a system of servers worldwide that work together to deliver web content to users based on their location. It stores copies of website data, including HTML pages, images, videos, and JavaScript files.
The main role of Content Delivery Networks (CDNs) is to reduce latency, speed up website load times, and overall improve the performance of the website. CDN is a tool that can improve user experience, lower bounce rates, and positively impact SEO. It does so by ensuring that content is delivered directly from edge servers.
