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

Summary

In this chapter, we discussed the basics of security frameworks as a starting point to define policies for cloud environments. We have learned that there are different frameworks and that it depends on the industry to determine the compliance requirements of a business. Next, we must decide which security controls to set to ensure that our cloud environments are compliant too.

One framework that is globally accepted and commonly used for clouds is CIS. For Azure, AWS, and GCP, we studied the CIS benchmarks. We learned that the CIS benchmarks for these cloud platforms greatly overlap, but also have specific settings that need to be implemented in the respective security suites – Azure Security Center, AWS Security Hub, and Google's Security Command Center.

In the last section, we learned the difference between security governance and security management, but also that one can't live without the other.

In the next chapter, we will dive into identity...
