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.

Integration of Application Insights and Azure Functions


Application Insights is used to monitor live web applications. Application Insights detects issues. It can therefore be useful in improving the quality and performance of the application. It supports applications based on .NET, Node.js, and J2EE.

Application Insights monitors request rates, dependency rates, response times, failure rates, exceptions, page views, load performance, AJAX calls, user and session counts, performance counters, host diagnostics, diagnostic trace logs, custom events, and metrics.

To integrate Azure Functions with Application Insights perform the following steps:

  1. Here, we will try to use Application Insights for the Azure Function App. We have already created the Function App. Let's create Application Insights and associate it with the Function App.
  2. Go to Application Insights.
  3. Click on Add:
  1. Give a Name.
  2. Select General in Application Type:
  1. Use the existing Resource Group and select Location.
  1. Click on Create:
  1. Once Application...
