During the 24th AzureHeads meetup, I delivered a presentation about three azure services, Azure Functions, CosmosDB and Signalr; I talked about websockets and the benefits compared to long polling and then, I built a stocks demo application using Azure Functions for the logic, Azure CosmosDB for the data persistence and then I showcase how is it is to add real-time updates to the end-user web app using an Azure CosmosDB feature called Change Feed and Azure SignalR service.

The audio is in Greek, so if you are brave enough with the language, enjoy 🙂
