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

Designing a network topology for multi-cloud – thinking ahead

Before designing the network topology, we need to answer one question: what does the business require in terms of connectivity? But there are a few more things to carefully consider before you start designing and implementing VPNs or ordering direct connectivity.

The first step is assessment. A company will already have a network. You will need to assess how that network is configured. How do users connect to systems? How do they access the internet? How is traffic routed through systems? How are these systems protected from a network perspective? Where are firewalls, the proxy, and the reverse proxy situated? Yes, this is all important before we start designing a connection to a public cloud.

Prerequisites for creating a network design

As already explained, most companies will use network services from a telecom provider. Part of the assessment, therefore, is to explore the offerings the telco has in terms...
