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

Chapter 14: Defining Security Policies

Whatever we do in the cloud, it needs to be secure. Cloud providers only provide tools. You need to define how to use these tools. In order to determine what these tools should do, you need to think about what type of assets you want to protect and how you need to protect them. There are quite a number of security baselines; for example, the baseline as defined by the Center for Internet Security (CIS), which provides guidelines.

We will learn what a security framework is and why it's important as a starting point for security policies. We will discover what we need to protect in our cloud environments. Next, we will look at the globally adopted CIS benchmark for Azure, AWS, and GCP and learn how to implement CIS using the security suites of these platforms. Lastly, we will learn what the difference is between security governance and management.

In this chapter, we're going to cover the following main topics:
