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.

Exploring Identity Patterns

In this chapter, we will finally put into practice the knowledge that we acquired throughout the book before now. We now know how the OpenID Connect (OIDC) and OAuth 2.0 protocols work and, most importantly, what authentication flows they enable.

Understanding the right scenario for an authentication flow is a key aspect for an enterprise architect during the design of an application: the patterns described in this chapter can be used as a quick reference to guide the decision-making process around the authentication and authorization of an application.

To make a parallel with the programming world, these patterns can be applied to authentication in the same way that today, we, as programmers, design and write the code of a modern cloud application architecture by leveraging software design patterns (e.g. Ambassador, retry, sidecar, etc.).

This chapter will give you the tools (or patterns) to choose the best authentication design for an application...
