Jo's Talk

Serverless, WebSockets and scaling. Oh my!

Serverless WebSockets sounds like a bit of a contradiction. Serverless implies that we’re not managing servers ourselves, they’ve been abstracted away for our convenience and WebSockets allow us to communicate between a ‘client’ and a ‘server’, so what happens when that server is ‘serverless’?! How can the connection be maintained without spiralling costs?

We choose serverless architectures because of their ease of scaling with demand, but if our demand is high, how do we manage our Websockets connections, which are notoriously difficult to manage at scale?

This talk will go over an introduction to serverless architectures and why we love them, an introduction to websockets and their fortes and foibles and how to build fully serverless realtime features into your apps.
