To get the most out of this book

To use the book efficiently, you should have some understanding of security solutions, Active Directory, access privileges/rights, and authentication methods. Programming knowledge is not required but will be helpful for using PowerShell or working with APIs to customize your solutions. Working through the first edition of the book is not a requirement for following the chapters in this book.

During the book, we will work entirely on the Azure platform itself. The only requirement is to have an internet connection and a Microsoft or Apple client computer. The labs can be undertaken free of charge for the duration of the several trial versions we use. We highly recommend that you shut down your virtual machines on Azure to save the runtime for working with your practical guidance. In Chapter 7, Deploying Solutions on Azure AD and ADFS, we will provide you the architecture overview with all the requisite information for sizing and the different products we use and will reference in the chapters. We also provide you the guidance to create public certificates with Let's Encrypt. One small cost requirement exists. If you want to run all the different labs, you need to have three public DNS domains registered, including access to the related public DNS. Bear in mind that this lab is for studying and testing functionality and not a representation of a productive environment. Follow the instructions in the chapters to arrange the correct resources. All the scripts and demo files are covered in the example code files, which you can download on the web page provided in the download the example code files section.
