Cloud Security Handbook

By: Eyal Estrin

Overview of this book

Securing resources in the cloud is challenging, given that each provider has different mechanisms and processes. Cloud Security Handbook helps you to understand how to embed security best practices in each of the infrastructure building blocks that exist in public clouds. This book will enable information security and cloud engineers to recognize the risks involved in public cloud and find out how to implement security controls as they design, build, and maintain environments in the cloud. You'll begin by learning about the shared responsibility model, cloud service models, and cloud deployment models, before getting to grips with the fundamentals of compute, storage, networking, identity management, encryption, and more. Next, you'll explore common threats and discover how to stay in compliance in cloud environments. As you make progress, you'll implement security in small-scale cloud environments through to production-ready large-scale environments, including hybrid clouds and multi-cloud environments. This book not only focuses on cloud services in general, but it also provides actual examples for using AWS, Azure, and GCP built-in services and capabilities. By the end of this cloud security book, you'll have gained a solid understanding of how to implement security in cloud environments effectively.

Chapter 12: Managing Multi-Cloud Environments

In previous chapters, we covered hybrid cloud and how to connect your on-premises data centers to Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP), and how to create a hybrid cloud architecture. In this chapter, we will cover one of the most complex scenarios in the cloud – managing multi-cloud environments. Multi-cloud is about using more than one cloud or cloud provider to setup a common environment, infrastructure, or even an application layer.

Organizations taking their first steps using cloud services consider a multi-cloud approach as a solution for protecting themselves against a vendor lock-in scenario – a scenario where our entire infrastructure or applications rely on a single cloud provider's ecosystem.

One of the questions organizations ask themselves is, what do we do if the cloud provider goes out of business? How do we migrate our assets to another cloud provider? In theory, a multi...
