A lot of .NET applications are written using WebAPI backend services. These services can be hosted using an AppService on Azure. The code in these WebAPIs is typically not very large and tends to go towards a microservice. But do I need a complete AppService in this case? In this talk, I show you a viable alternative: Azure Functions. We will cover what Azure Functions is all about, and of course, we will write some functions together to show you what you can really do with Azure Functions.
