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.

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 review the recommended ways to implement authentication in different contexts. We covered user authentication in a web application scenario in a dedicated section and then reviewed the differences between user authentication from a native application standpoint and from a SPA standpoint as well. Throughout the chapter, we covered the advantages and disadvantages and the specific OAuth 2.0 flow to adopt according to the given circumstances. As we outlined in the chapter, whenever applicable, the Authorization Code Grant flow with PKCE is the recommended OAuth flow to adopt.

In the next chapter, we’re going to describe how these authentication patterns and OAuth flows relate to current IT trends, API proliferation, and service meshes, and, in general, how to match new trends to the concepts of authentication.
