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

Security starts with IAM: making sure that we have control over who's accessing our environments and what they are allowed to do in systems. In this chapter, we have learned what identities are and that we need a central identity store. From this identity store, we have to federate between the different cloud solutions that an enterprise has. We have learned how we can set up federation and how IDaaS can be a good solution for this.

We've studied concepts of authorization and authentication in the major cloud platforms. An important concept is least privilege. After this chapter, you should be able to make a distinction between standard accounts and privileged accounts. Lastly, we have learned what benefits PAM can have in securing access to our clouds.

The reason to have our cloud environments maximally secured is to protect our data. We have studied identities, access management, and security policies to protect our infrastructure. In the next chapter, we...
