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.

Active Directory Federation Services (AD FS)

Historically, AD FS has been Microsoft’s solution to federated authentication. AD FS tightly integrates with AD DS by acting as a sort of protocol translator that allows federated applications to use modern protocols, while, under the hood, actually authenticating the users against AD Domain Controllers through Windows authentication (Kerberos or NTLM) without the application being aware of where the user’s credentials are stored.

The infrastructure of AD FS is very simple and is made up of a pair of server roles: AD FS servers and AD FS proxy servers. The former are installed within a company’s internal network and provide their functionality, including single sign-on (SSO), to users connecting from within the organization premises or connected through a virtual private network (VPN). The latter are typically installed in a demilitarized zone (DMZ) network, which is logically separated from the internal network and...
