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

In this chapter, we explored the different concepts of connectivity to public clouds. Without connectivity, nothing will work – or at least nothing will be reachable. We have learned the major differences between the VPN concepts and the direct connectivity propositions of Azure, AWS, and GCP. An important lesson is that VPN connections are fine at lower bandwidths, but enterprises typically need more than that, and they should consider moving to direct connection solutions. To design a connectivity strategy for our business, we need to take some key parameters into account—the cost, internet access, security, and service levels.

From a technology perspective, we have studied concepts such as SDN and have also learned that you can extend an on-premises network to a public cloud with concepts such as VMware's NSX. Connectivity is king and therefore you also need to have a basic understanding of the various protocols that networks use to establish a connection...
