Speaker bio
Gaurav is a Cloud Architect at Hotstar, India’s leading OTT provider that holds a global concurrency record for live streaming to 25Mn+ viewers. At Hotstar, he loves building cost-efficient infrastructure that can scale to millions in minutes. He is also passionate about chaos engineering and cloud security.

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.

Here after 54 million in IND v NZ Semi-Final of 2023, crazy to think that the new record is DOUBLE than this!

[theoutlet]

wow those numbers are insane. I would love to see a cost graph during the match as well

[JohnSnow-giiv]

Watching this after 58M concurrent users in IND vs AUS final.

And now jio hired all hotstart employee to build juocinema 😅 and now jio is also able to handle that load. Good video❤

[ShivamSharma-jxi]

Great job hotstar team . Kudos from a Indeed engineer (76million scale)

[JZL]

pretty fascinating that if service is degraded they'll just allow anyone to watch the video without logging in or paying. Very nice of them and makes sense, for live sports matches, better to let everyone in than deal with all the headlines of "match went down 5 minutes before game ended"

[panditvenkatesh]

Good info for Perf test - enthusiasts, well explained

[sahiljain]

streaming services: oh no.., spikes are nasty, ,
cable: hold my beer...

[abridgetool]

After watching this video, I am like
"Asli kaam to ye log kar rahe hain, hum to bus apni... "

Today, Pak vs India match in NewYork was Streaming on Tamasha App and there were 69+ millions viewers 😅

[indianmemeswaala]

Jio cinema handled 2.2 cr (22 million) concurrent traffic for a normal ipl 2023 league match of CSK vs RR
Wonder what will be the live numbers in IPL 2023 final

[omkarachary]

Great job hotstar team . Kudos from a Cleartax Architect (60million scale).

[Indian-JaiHindusthan]

Awesome.. what is underlined load testing tool used to orchestrate?

[vijayrk]

Amazing Man. Hats off Gourav and team!

[ksb]

I selected this video very eagerly on how to learn, after knowing it is the same game that gave me traumatic vibes

[darkwhite]

why hotstar didn't use private cloud in aws? why use public cloud?

[Aloktiwari-sfim]

People directly close the tab most of the time in such cases.

[vaibhavmishra]

The final spike and dip after Dhoni started batting definitely reads 7
Thala for a reason 💪

[kapilpatel]
