This chapter will take us into the realm of serverless computing. Just what is serverless computing, I hear you ask? Well, the answer is really simple once you grasp the idea that the term serverless computing has nothing to do with the lack of a server. It is quite the opposite, in fact.
In this chapter, we will have a look at:
- Creating an Azure Function
- Testing your Azure Function in the browser
- Calling an Azure Function from an ASP.NET Core MVC application
We will be creating a simple Azure Function that uses regular expressions to validate an email address. You need to keep in mind that Azure Functions are small pieces of code in the cloud. Do not think of them as large sections of complicated code. The smaller the better.
