A popular content delivery network (CDN) example is Akamai. CDNs optimize the delivery of web content by distributing it across a network of servers, enabling faster loading times and improved website performance. They reduce latency by caching content closer to users and balancing traffic loads, ensuring reliable access, even during peak times. CDNs also enhance security by providing DDoS protection and secure data transmission. This technology is vital for websites and applications that handle high volumes of traffic or demand low response times.
