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.

Trends in API Authentication

The previous chapter introduced you to the authentication and authorization flows available in the OAuth literature; we proposed a mapping between specific applications’ architectures and recommended an authentication and authorization flow. When you are looking for guidance on which OAuth flow to adopt, according to a specific need, the previous chapter provides a reference point, but it is important to outline that it is meant to provide guidance and answers bounded to specific needs. It does not help an organization to understand how to create governance and blueprints around authentication, as the concept is way more complicated than individual scenarios produced to address specific requirements.

The aim of this chapter is to report how authentication and authorization map to an API enterprise’s landscape and to discuss the implications of authentication and authorization at scale.
