Multi-Cloud Architecture and Governance

By: Jeroen Mulder

Overview of this book

Multi-cloud has emerged as one of the top cloud computing trends, with businesses wanting to reduce their reliance on only one vendor. But when organizations shift to multiple cloud services without a clear strategy, they may face certain difficulties, in terms of how to stay in control, how to keep all the different components secure, and how to execute the cross-cloud development of applications. This book combines best practices from different cloud adoption frameworks to help you find solutions to these problems. With step-by-step explanations of essential concepts and practical examples, you’ll begin by planning the foundation, creating the architecture, designing the governance model, and implementing tools, processes, and technologies to manage multi-cloud environments. You’ll then discover how to design workload environments using different cloud propositions, understand how to optimize the use of these cloud technologies, and automate and monitor the environments. As you advance, you’ll delve into multi-cloud governance, defining clear demarcation models and management processes. Finally, you’ll learn about managing identities in multi-cloud: who’s doing what, why, when, and where. By the end of this book, you’ll be able to create, implement, and manage multi-cloud architectures with confidence

Designing access management across multi-cloud

In the previous section, we learned that we need to have federation with AD in our public cloud environment. The next question is: how do we do that? Azure uses Azure Active Directory (AAD). Just as a reminder: AAD is not the same as AD. AAD is an authentication service in Azure, using AD as the directory. Microsoft positions AAD as IDaaS, something that we will explore in more detail in the last section of this chapter, Enabling account federation in multi-cloud. The primary function of AAD is to synchronize identities to the cloud – Azure – using the existing AD. For the synchronization, it uses Azure AD Connect.

With AAD, enterprises will have a system that provides employees of these enterprises with a mechanism to log in and access resources on different platforms. That can be resources in Azure itself or resources such as applications hosted on systems in the corporate network.

But AAD also provides access to...
