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

Setting up the requirements for integrated security

Before a company gets into buying licenses for all sorts of security tools, security architects will need to gather requirements. That is done by the following four stages that a security team needs to cover:

  1. Detect: Most of the security tools focus on detecting vulnerabilities and actual attacks or attempts to breach systems. Some examples are endpoint protection, such as virus scanners and malware detection, and Network Traffic Analyzers (NTA). In multi-cloud, architects need to make sure that detecting systems can operate on all platforms and preferably send information to one integrated dashboard.
  2. Analyze: This is the next phase. Detection systems will send a lot of data, including false positives. Ideally, security monitoring does a first analysis of events, checking them against known patterns and behavior of systems and users. This is the first filter. The second phase in the analysis is prioritization, which is...
