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

Managing security policies

It doesn't stop with implementing security policies. We need to have governance in place to manage the policies. Governance is required on two levels:

  1. The security policies themselves, auditing these to the compliancy frameworks that a business has to adhere to.
  2. The technical implementation of the security policies, keeping the monitoring up to date, making sure that all assets are indeed tracked against the policies.

The first level is the domain of people concerned with the security governance in a business, typically, a Chief Information Security Officer (CISO) or Chief Information Officer (CIO). They need to set directions for security policies and make sure that the business is compliant with the security strategy, industry, and company frameworks. The CISO or CIO is also responsible for assurance from internal and external auditing.

Level two is more about security management, concerning how to deal with security risks in...
