The talk will focus 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. It will talk about challenges in scaling infrastructure for millions and how to overcome it, how we run gamedays before actual games, how we use load testing monster called Hulk to prepare for peak traffic and also how we add chaos (engineering) in between all these epic scale madness.

    Thanks for the proposal, Gaurav. We can confirm your talk for Rootconf Hyderabad, since we are getting overbooked for Rootconf Pune. We’d like you to run a Birds of Feather (BOF) on auto-scaling for Rootconf Pune. Will you be interested in doing this? The editorial team will help you with finding other discussants for the BOF.
