How Hotstar.com scales for millions of concurrent viewers

Hotstar (Disney’s OTT streaming service) live streamed the recent India Pakistan  T20 cricket match to 1.2 crore viewers!

Back in 2019, Hotstar had already created a global record for live streaming to 25.3 million concurrent viewers during the rain-affected World Cup Cricket match between India & New Zealand. 

In the following 2 videos delivered at separate events, Gaurav Kamboj, Cloud Architect at Hotstar, explains why traditional autoscaling doesn’t work for Hotstar and other interesting facets about how the streaming site is architected to run on AWS.
