Stop me if you’ve heard this one: A lawyer, a plumber, and an Azure Function walk into an espresso bar. The lawyer immediately announces, “I make $400 an hour. The lattes are on me!”
Just because somebody codes and deploys an Azure Function does not immediately confer serverless status on that code. Microsoft offers several ways to host Azure Functions, and, by my accounting, https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale are fully “serverless.”https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale
The other hosting plans for Azure Functions, which involve various configurations of the Azure App Service, as well as Kubernetes and Arc, certainly qualify as cloud architectures, but just not fully serverless architectures.
