Nowadays, web apps that require a user to reload a page in order to see updated information seem outdated. Users expect duplex communication between browser and backend to enable updates and notifications if something interesting happens on the server-side. WebSockets and SignalR are great technologies enabling that. In the past, building and running scalable web apps with these technologies was a real challenge. Microsoft has added a new serverless SignalR-service to its Azure cloud that frees developers from having to care for scaling manually. Additionally, Microsoft added support for combining the new SignalR-service with its serverless Azure Functions-framework. A dream team for real-time web apps was born. In this talk, long-time MVP and MS Regional Director Rainer Stropek demonstrates the combination of Azure SignalR with Azure Functions based on an end-to-end sample. Be prepared for a session with no slides, just coding.
