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

Global admin galore – the need for demarcation

Typically, when we talk about demarcation in cloud models, we refer to the matrix or delineation of responsibility: who's responsible for what in IaaS, PaaS, and SaaS computing? The following diagram shows the very basics of this matrix:

Figure 6.6 – Demarcation model in cloud deployment

However, we need a much more granular model in multi-cloud. We have been discussing policies throughout this chapter and by now, we should have come to the conclusion that it's not very easy to draw some very sharp lines when it comes to responsibilities in our multi-cloud environment. Just look at the solution stack – even in SaaS solutions, there might be certain security and/or compliancy policies that the solution needs to adhere to. Even something such as an operating system might already be causing issues in terms of hardening: are monitoring agents from a PaaS provider allowed or not? Can we...
