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.

OAuth 2.0 and OIDC

This chapter is going to get you started on the technical journey to understand the advanced concepts that will be covered in the following chapters.

In this chapter, we are going to learn about the basics of the most used authentication protocol for cloud applications, which is OAuth 2.0, and we are going to appreciate why OAuth 2.0 has become the de facto standard in web authentication.

This chapter will also introduce you to OpenID Connect (OIDC).

OIDC extends the OAuth 2.0 protocol by introducing new flows, reusing some existing ones, and making the user, not the application, the center of these flows.

In this chapter, we will go through and learn all about the basics of OAuth 2.0 and OIDC, their similarities and differences, where they can be used and why, and what the actors that participate in authentication and/or authorization flows are.

This chapter will not analyze the flows of these protocols in depth; those will be covered in the next...
