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

Validating invoices

Validating invoices has nothing to do with checking whether a cloud provider has charged us the correct amounts. Cloud providers have fully automated this process, so you may rest assured that if you or your company uses a resource in their cloud, it will show up in the bill. Validating invoices is about checking whether invoiced costs correspond with the forecasted usage of your company. Are you on budget or are you overspending? Are there resources on the bill that you aren't using anymore? And if so, why didn't you delete these resources?

Some key decisions will need to be made. These decisions are the same for all clouds covered:

  • Will the organization use one or multiple billing accounts? If you want a project manager to be able to validate the costs for a specific project or in a particular environment, then he or she should be granted access to view these costs. As we have seen in the previous section, we can set these privileges granularly...
