A CDN provider (Content Delivery Network provider) is a service that helps deliver web content quickly and efficiently to users around the world. By using a network of servers located in various geographic locations, a CDN provider stores copies of your website's content. This means that when someone visits your site, they can access it from a server that is closer to them, reducing loading times and improving the overall user experience. CDN providers also enhance website performance and security. They can handle large amounts of traffic, which is especially useful during peak times or events. Additionally, they often offer features like DDoS protection and SSL certificates to keep your site safe from attacks and ensure secure connections for users.
