You may not have realized it at the time, but it's quite possible you've used Akka without knowing it.
Some of the most admired brands in the world know that when it comes to providing extreme throughput, massive concurrency, and dependable self-healing against cluster and network failures, Akka is the leading Reactive technology on the market. Let's take a look at how Akka powers streaming entertainment and gaming experiences for over 400 million users around the world, with significantly lower infrastructure costs than many alternatives.
We'll start with the big player (no pun intended) in the room: Fortnite.
Fortnite has exploded in popularity over the past nine months, growing by 100x, according to Epic. Now the company is looking to technologies like Kubernetes to help it manage all the back-end servers and services, including dozens of microservices written in Java, Akka, and Go, that it needs to run its games.

While some of us were sleeping, Fortnite by Epic Games erupted into a global phenomenon in 2017, gathering over 125 million users in the first year of operations. Now at 250 million users and growing, Epic Games has redefined what it means to engage a global audience at massive scale–recently supporting 12.3 million concurrent gaming sessions at once. It is great to see them using Akka under the hood to power their back-end servers and tens of microservices, as Chris Dyl, Director of Platform at Epic Games, revealed at AWS re:Invent 2018.
Founded in 2008, iHeartRadio is an American free broadcast, podcast and streaming radio platform. With over 128 million users in 2019, they are effectively the umbrella brand for the largest radio broadcaster in the United States. As an adopter of Akka back in 2015, iHeartRadio was able to jump from 70 million to nearly double that in a few short years, backed by a Reactive system that offers transparency, resilience, and massive scalability within and across their microservices.
