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.

Common antipatterns

Think about an organization where the proliferation of APIs has created many different islands with different APIs made using different technologies and standards. It is very common to see different teams attempting to create standards that are not widely applicable.

A typical case we want to mention is something that happened to one of our customers. The infrastructure team had been empowered by the management to resolve the problem of API and application proliferation and to bring order to the APIs and the applications in the company’s landscape. We are talking about a company that had more than 1,000 applications and APIs.

The infrastructure team defined a gateway to validate tokens and prevent any request from reaching the backend without the validation of a token, as follows:

It is important to understand that this pattern has been applied to the entire application portfolio...
