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

Implementing security policies

We have studied the compliance and security frameworks and we've defined our security baseline. Now we need to implement it in our cloud environments. In this section, we will explore implementations in the major clouds, using the native security platforms. Since CIS is widely and globally adopted as the baseline for security policies, all sections will explore specific settings that CIS benchmarks recommend for the different platforms. Links to the benchmarks are provided in the Further reading section of this chapter. CIS provides recommendations, but also documents how policies should be implemented.

For example, in GCP there is a recommendation to "ensure Cloud Audit Logging is configured properly across all services and all users from a project." CIS benchmarks also guide users to find where the setting needs to be configured and how; in this example, by going to audit logs at https://console.cloud.google.com/iam-admin/audit or...
