Cloud Identity Patterns and Strategies

5 (1)
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.

Part 1: Impact of Digital Transformation
Part 2: OAuth Implementation and Patterns
Part 3: Real-World Scenarios


In this chapter, we had the opportunity to understand how the current trends map to the topic of authentication, when OAuth is required, and when tools can help to facilitate authentication without OAuth.

We started the chapter by outlining the API proliferation phenomenon and the related implications. We then showed you a diagram to outline how APIs are typically organized within a company and how they are classified, as well as the authentication requirements for each classification. We also reported the modern way to manage services and APIs with a service mesh and the related authentication implications.

This chapter also outlined bad practices, such as multiple IdPs, and provided an example of a real-world antipattern that we encountered during our work. In the next chapter, we’re going to be a little more technical and focus on some of the most widely adopted cloud IdPs.
