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

Understanding identities and roles in the cloud

Everything in the cloud has an identity. There are two things that we need to do with identities: authenticate and authorize. For authentication, we need an identity store. Most enterprises will use Active Directory (AD) for that, where AD becomes the central place to store identities of persons and computers. We won't be drilling down into the technology, but there are a few things you should understand when working with AD. First of all, an AD works with domains. You can deploy resources – VMs or other virtual devices – in a cloud platform, but if that cloud platform is not part of your business domain, it won't be very useful. So, one of the key things is to get resources in your cloud platform domain-joined. For that, you will have to deploy domain services with domain controllers in your cloud platform or allow cloud resources access to the existing domain services. By doing that, we are extending the business...
