Cloud Identity Patterns and Strategies

By: Giuseppe Di Federico, Fabrizio Barcaroli

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.

Understanding the basic terminology

Before diving into each pattern, we will present you with some terminology that will be used throughout the following presentation of different patterns. Then, we’re going to review the patterns recommended for different application styles:

  • Application identity

As we’ll see later, there are different kinds of applications that exist. It’s important to grasp the concept of application identity though before expanding to examine the different types of applications that can be encountered.

Application identity is a concept that is tightly coupled with the OIDC and OAuth 2.0 authentication protocols. When interacting with an identity provider, an application must have and use an identity that the identity provider knows, an identity that an administrator has previously registered as part of the application configuration. Typically, an OIDC or OAuth 2.0 flow requires two application identities to be registered: a...
