Serverless WebSockets at Scale

Building high-scale WebSocket services is notoriously difficult. At DAZN, we wanted to do exactly that, but can serverless technologies make it easier? We’ll follow the journey of building and testing a WebSocket service, capable of handling millions of concurrent connections, on AWS.

This talk will give an overview of the options available on AWS and deep-dive into the solution and architecture we designed. We’ll show our load tests and some interesting learnings and limitations that we discovered along the way.
