Cloud Identity Patterns and Strategies

Overview of this book

Identity is paramount for every architecture design, making it crucial for enterprise and solutions architects to understand the benefits and pitfalls of implementing identity patterns. However, information on cloud identity patterns is generally scattered across different sources and rarely approached from an architect’s perspective, and this is what Cloud Identity Patterns and Strategies aims to solve, empowering solutions architects to take an active part in implementing identity solutions. Throughout this book, you’ll cover various theoretical topics along with practical examples that follow the implementation of a standard de facto identity provider (IdP) in an enterprise, such as Azure Active Directory. As you progress through the chapters, you’ll explore the different factors that contribute to an enterprise's current status quo around identities and harness modern authentication approaches to meet specific requirements of an enterprise. You’ll also be able to make sense of how modern application designs are impacted by the company’s choices and move on to recognize how a healthy organization tackles identity and critical tasks that the development teams pivot on. By the end of this book, you’ll be able to breeze through creating portable, robust, and reliable applications that can interact with each other.

Registering and configuring applications

In the AAD basics section, we analyzed the twofold nature of an application in AAD. We know that an application has a definition that lives in the home tenant (the tenant where it has been effectively created) and a service principal, which is an instance of an application definition that can live both in the home tenant and within an external AAD tenant, where it will be created as a dedicated new instance. The service principal inherits the application definition permissions and applies them to the resources that live in the same tenant where it has been instantiated.

AAD provides several ways to manage its services:

The examples that will be described in this paragraph use the Microsoft Entra admin center, which has been released recently and still has...
