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.

Architecting the solution


The following diagram shows the solution's architecture:

As we discussed at the start of the chapter, the user will fill in the form and submit the data. Once the data gets submitted, the HTTP trigger of the Azure Function processes the request and puts the data in the database.

In the preceding architecture diagram, the user will fill all the details in the form. Once the user submits the form, HttpRequest will be sent to Azure Function and HttpTrigger gets fired. HttpTrigger executes the code, which stores user details in Cosmos DB.

Now, in the next section, we will start our project.
