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

Defining architecture principles for multi-cloud

We'll start this chapter again from the perspective of the enterprise architecture. As we have seen, the Architecture Development Method (ADM) cycle in TOGAF is a guiding and broadly accepted framework used to start any enterprise architecture. In Chapter 2, Business Acceleration Using a Multi-Cloud Strategy, we learned that the production cycle for architecture starts with the business, yet there are two steps before we actually get to defining the business architecture: we have a preliminary phase where we set out the framework, and the, there's the architecture principles. These feed into the very first step in the actual cycle, known as architecture vision, as shown in the following diagram:

The key to any preliminary phase is the architecture principles; that is, your guidelines for fulfilling the architecture...
