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.

OAuth and OIDC basic concepts

The basic architecture of applications that are composed of multiple tiers separating the presentation from the business logic and data, with the business logic exposed through a set of services, has largely gone unchanged for the last decade.

However, the environment in which these applications are expected to operate has completely changed in this same timeframe. Today, you cannot just offer a simple browser-based website; you need to also support IoT devices (such as presentation screens, smart devices, sensors, and electrical appliances) and mobile clients, and these mobile clients must be supported across a broad range of devices, mostly based on iOS, Android, or Windows.

In today’s landscape, users expect applications and services to interoperate – to be able to be used together. For example, users expect to be able to post the latest purchase they have made from Amazon or ASOS to their Facebook wall or share a photograph on Instagram...
