Learning Azure Functions

By: Mitesh Soni, Manisha Yadav

Overview of this book

Functions help you easily run small pieces of code in cloud with Azure functions without worrying about a whole application or the infrastructure to run it. With Azure functions, you can use triggers to execute your code and bindings to simplify the input and output of your code. This book will start with the basics of Azure Functions. You will learn the steps to set up the environment and the tools that we will be using in the further chapters. Once you have a better understanding of this, we will be creating our first hello world function app. Later you will be introduced to triggers, how they are used to activate a function, and how binding can be used to output results of a function.You will also explore the steps to create an assembly with complex functionality that can be used by functions. Next, this book will teach you to scale your functions and use them to process data, integrate systems, and build simple APIs and microservices. Finally, this book will cover some diagnostic techniques with Azure App services and best practices of working with Azure Functions. By the end of this book, you will be well-versed with the techniques of scaling your Azure functions and making the most of serverless architecture.

Finally, we have reached the end of the chapter. In this chapter, we learned about Webhooks. We discussed the introduction of Webhooks and how they are different from APIs. We have created a JavaScript function triggered by a Webhook, which gets triggered when the new resource group is added to Azure. We created an activity alert in Azure monitor for a Webhook and bound it to our Azure Function.

Then, we tested our function by creating resource groups. Further, we saw how to bind the Webhook to our Azure Function. We bound it as an output to our HTTP trigger. In the last section of this chapter, we discussed events in relation to Azure Functions.

In the next chapter, we will do some exercise that will use all the concepts we have explained so far and create a real-life example. We will give an outline of the project, the solution, and its implementation as well.
