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 network protocols in multi-cloud

We came across a lot of acronyms and terms in this chapter. If you're not a network engineer, some of these acronyms might not directly ring a bell. Yet, things such as BGP, ASN, and TLS are crucial in understanding how connections work. The good news is, any public cloud is internet-based. Without the internet, we wouldn't have the cloud in the first place. So, protocols such as IP, HTTP, and HTTPS are really crucial. But what about the rest? In terms of cloud connectivity, there is quite some more that needs to be taken into consideration. After all, we do want our connections to be secure and only going in the direction we want them to go. On top of that, we have to enable connections to set up communication between targeted resources. That requires these resources to speak the same language.

Cloud computing is hosted over the internet through a network connection. The required and crucial protocols are as follows:
