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.

Authentication challenges for microservices integration

All the patterns exposed so far have focused on internal authentication within a component of an application. We have seen scenarios where we wanted to authenticate each microservice and when we wanted to authenticate them based on the domain to which they belonged.

In real-world scenarios, the context is usually way more complex and we usually come up against integration requirements that require us to consider authentication beyond the remit of the patterns described so far.

The purpose of this chapter is to situate integration within the bigger picture and review how it is possible to combine the patterns explained so far to provide a more holistic solution. This chapter will focus on inbound integrations, which are the capabilities or APIs that the application needs to expose to external or third-party systems.

Inbound integrations are the calls to which the application is expected to reply, submitted from external...
