CDN (Content Delivery Network)
A CDN distributes video streams across geographically distributed servers, ensuring viewers connect to nearby servers for faster delivery and lower latency. Without a CDN, all viewer traffic connects to a single origin. With 100,000 concurrent viewers, that is impossible. CDNs scale by distributing viewers across thousands of edge servers. A viewer in Abu Dhabi requesting a stream connects to an edge server in Abu Dhabi, not travelling around the world.
