Learning Azure Functions

First Function App - Anatomy and Structure of a Function App

"Where there is a will, there is a way. If there is a chance in a million that you can do something, anything, to keep what you want from ending, do it. Pry the door open or, if need be, wedge your foot in that door and keep it open."
- Pauline Kael

There is always a first time for everything. Here in this chapter, we will take one scenario and then we will try to complete the scenario with Azure Functions so that we can understand how Azure Functions work, and the different resources of Microsoft Azure that are involved in the whole scenario.

In this chapter, we will focus on creating our first Azure Function. We will create an Azure Function App and then we will create an Azure Function with triggers and output bindings.

We will also troubleshoot if we find any issues in the Azure Function. One of the most...

Anatomy of Azure Functions

Let's understand the different components or resources that are used while creating Azure Functions.

The following image describes the Functions in Azure in different pricing plans:

Azure Function App

A function app is a collection of one or more functions that are managed together. All the functions in a Function App share the same pricing plan and it can be a consumption plan or an App Service plan. When we utilize Visual Studio Team Services for Continuous Integration and Continuous Delivery using build and release definitions, then the Function app is also shared. The way we manage different resources in Azure with the Azure Resource Group is similar to how we can manage multiple functions...

Setting up a basic Azure Function

Let's understand Azure Functions and create one in Azure Portal.

  1. Go to https://portal.azure.com. Click on Function Apps in the left sidebar:

There is no Function App available as of now.

  1. Click on the plus + sign and search for Function Apps. Then click on Create:
  1. Provide the App name, Subscription details, and existing Resource Group. Select Consumption Plan in Hosting Plan. Then select Location:
  1. Select Create New in Storage and click on Create:
  1. Now, let's go to Function Apps in the left sidebar and verify whether the recently created Function App is available in the list or not:
  1. Click on the Function App and we can see the details related to the Subscription, Resource group, URL, Location, App Service Plan / pricing tier.

We can stop or restart the function from the same pane.

  1. The Settings tab provides details on...

Summary

Finally, we have created our first function that processes a photograph and creates a thumbnail for a photography competition scenario.

We have also seen the anatomy of Azure Functions and covered the troubleshooting of issues that can occur in the Azure Function processing.

So, we have covered all the basic things to execute a simple function with triggers and output binding.

In the next chapter, we will discuss triggers in detail.

Key benefits

  • Learn to develop, manage, deploy, and monitor Azure functions in any language.
  • Make the most out of Azure functions to build scalable systems.
  • A step-by-step guide that will help you eliminate the pain points of implementing a serverless architecture.

Description

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.

Who is this book for?

This book aims at IT architects and developers who want to build scalable systems and deploy serverless applications with Azure functions. No prior knowledge of Azure functions is necessary.

What you will learn

  • Understand the folder structure of a function and the purposes of the files
  • Deploy a function and test it
  • Explore the common triggers that are used to activate a function
  • Discover how bindings can be used to output the results of a function
  • Build a dll that has functionality that can be leveraged by a function

This book clearly wasn't edited before being published. The information is OK, but the broken English is difficult to decipher sometimes and many examples are missing crucial steps.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
