How Netflix can live stream BTS Gwanghwamun concert to 300 million subscribers

A BTS concert in Seoul\'s Gwanghwamun on March 21 will be broadcast live worldwide on Netflix to more than 300 million subscribers, drawing attention for its technology. Unlike video-on-demand, live streaming must capture and encode video in real time and deliver it simultaneously to hundreds of millions of devices. Netflix uses an AWS-based live infrastructure with dual-region redundancy, real-time encoding and distribution via its Open Connect CDN. The stream will process up to 38 million system events per second.
