Because they are priced on a pay-as-you-use model, you only pay for the actual computing power user. When the user load is high on your web application, the function automatically scales as required to meet the demands of the application accessing it.
We took a look at the process of getting to know the code in our Azure Function by posting the URL into the browser manually. Then, we created an ASP.NET Core MVC application that consisted of a single login page. We then had a look at how to use the Azure Function to validate the email address entered on the login screen. Azure Functions are an exciting technology to start using. There is still a lot to learn, and not enough left of the chapter to discuss this serverless technology. If this technology interests you, explore some of the other Azure...
