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.

This is the second to last chapter and we are about to finish our journey. We have covered how to monitor a Functions App using the available monitoring in the Function App itself.

Basic monitoring includes the success and error count of code execution and logs. However, it is important to have detailed analysis as well; thus, we utilized Application Insights to monitor Azure Functions.

We have integrated Azure Functions with Application Insights.

Once we decide on the usage of Azure Functions, it is important to consider pricing also, so we have also discussed the consumption plan and App Service plan to host Azure Functions.

In the next chapter, we will cover basic examples of other languages, such as Python, PHP, and so on.
