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.

Backend authentication challenges in the real world

In the previous section, we focused on how the number of IdPs used to authenticate the customer of a company can affect the design.

In this section, we are going to be focused on server-to-server authentication, a topic that is becoming even more important with cloud-born applications.

In the consumer example proposed in the previous section, having multiple IdPs for backend authentication (or server-to-server authentication) within an organization can lead to an even worse scenario than the one analyzed in the previous section.

Let’s forget user, consumer, or customer authentication for a minute; in other words, let’s forget the interactive authentication made by a human that was covered in the previous section, and let’s go deeper into analyzing backend authentication.

As covered in Chapter 1, Walkthrough of Digital Identity in the Enterprise, digital transformation and the cloud are impacting the...
