CMY302: Scaling Hotstar.com for 25 million concurrent viewers

This session focuses on why traditional autoscaling doesn't work for Hotstar (Disney's OTT streaming service), who recently created a global record for live streaming to 25.3 million concurrent viewers. We talk about challenges in scaling infrastructure for millions and how to overcome them, how Hotstar runs gamedays before facing live games, how it uses a load-testing monster called Hulk to prepare its platform for 50M peak. We also learn how the company uses chaos engineering to overcome real-world problems and achieve this scale.
