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 security policies

Let's start from our traditional, on-premises data center—a building traditionally used to host physical equipment that runs applications and stores data. The building is very likely secured by a fence and heavy, locked doors that can only be opened by authorized personnel. Access to the computer floors is also secured. There may be guards in the building or CCTV systems watching over equipment 24 hours a day. The next layer of defense is the access to the systems and data. Access to systems is strictly regulated: only authorized and certified engineers may access the systems. It's all common sense when it comes to running systems in a physical data center.

You would be surprised to see what happens if companies move these systems to cloud environments with Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) solutions. For some reason, companies tend to think that by moving systems to...
