Serverless computing has been on a rapid rise in recent years and many services are popularised. One of the lesser-known services is Azure SignalR Serverless which can be used with Azure Functions.

Amongst other things, SignalR can push or broadcast information from a back-end function at any time to any front-end web application that has subscribed. This allows for real-time updates of data on websites, multiplayer games, polls, interactive chatbots and various other uses.

In this introductory session, we run through the theory and possible uses of SignalR before looking at how to create a simple application using Serverless SignalR with Azure Functions. Finally, we will finish by comparing it to Azure Web PubSub and seeing why you would select one over the other.
