CDN Content delivery network (CDN) has become an essential component of modern web development, revolutionizing the way websites deliver content to users. CDN is a network of servers distributed geographically to deliver web content more efficiently to users based on their location. In today's fast-paced digital world, where website speed and performance are crucial factors for user experience and SEO rankings, CDN plays a crucial role in enhancing website performance. By caching content on servers located closer to users, CDN reduces latency and accelerates content delivery, resulting in faster loading times and improved user experience. Additionally, CDN helps to distribute the load on a website's server, reducing the risk of crashes during high traffic periods. Moreover, CDN provides an added layer of security by protecting websites against DDoS attacks and cyber threats. Overall, CDN has become a fundamental tool for web developers and website owners to optimize performance, enhance user experience, and ensure the reliability and security of their websites.
