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.

Supported authentication protocols

AAD supports several authentication methods. Here’s the complete list at the time of writing:

  • Header-based authentication: This authentication pattern, which involves forwarding HTTP headers from a client application to a destination web application, is supported only when using the AAD Application Proxy service. AAD Application Proxy is a service that comprises two distinct components, one of which runs in the cloud and one of which runs on-premises (through the means of a connector), that allows us to publish on-premises applications that still leverage legacy authentication protocols to the internet.
  • LDAP authentication: Support for LDAP authentication is provided only through AD DS, which is a component, briefly described in the previous chapter, that must be deployed within an Azure Virtual Network and leverages identities that come from the synchronization of on-premises Active Directory forests. AD DS is useful in specific...
