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

The provisioning and consumption of resources in public cloud platforms

Before we dive into cost control in the provisioning of resources, we need to understand how resource provisioning works in the public cloud. There are lots of different ways to do this, but for this chapter, we will stick with the native provisioning tools that Azure, AWS, and GCP provide.

There are basically two types of provisioning:

  • Self-provisioning
  • Dynamic

Typically, we start with self-provisioning through the portal or web interface of a cloud provider. The customer chooses the resources that are needed in the portal. After confirmation that these resources may be deployed in the cloud environment, the resources are spun up and made available for usage by the provider.

The resources are billed by hour or minute unless there is a contract for reserved instances. Reserved instances are contracted for a longer period—1, 3, or 5 years. The customer is guaranteed availability...
