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.

Chapter 9. Working with Different Languages

"Elegance is not a dispensable luxury but a factor that decides between success and failure"

– Edsger Dijkstra

In this chapter, we will explore Azure Function with other languages. Up to now we have seen examples of Azure Function in JavaScript.

We can write Azure Functions in many languages such as C#, Python, F#, PHP, and JavaScript.

In this chapter, we will write Azure Functions in the following languages:

  • The Python Function App
  • The PHP Function App

Python as an object-based subset is roughly equivalent to JavaScript. Like JavaScript, Python supports a programming style that uses simple functions and variables without engaging in class definitions. Python, on the other hand, supports writing much larger programs and better code reuse through a true object-oriented programming style, where classes and inheritance play an important role. Python has built-in list and dictionary data structures, which can be used to construct fast runtime data structures...
