A CDN provider, or 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, CDN providers store copies of websites, images, and videos. This means that when someone accesses a website, the content is delivered from the nearest server, reducing loading times and improving the overall user experience. CDN providers also enhance website security and reliability. They can protect against traffic spikes and cyberattacks, ensuring that websites remain accessible even during high demand. Popular CDN providers include Cloudflare, Akamai, and Amazon CloudFront.
