Summary

In this chapter, we learned about what the cloud is and the different deployment, delivery, and consumption models of the cloud. Enterprises recognize the business value of the cloud and how a hybrid multi-cloud approach is emerging as a key ingredient in successful digital transformation journeys. There are major observable changes across how applications are built, data is managed, integrated, and operated at scale. Security is a cross-cutting concern in all these areas.

All the security components and architecture required for this digital transformation journey needs to be carefully rethought – identities, networks, apps, data, integrations, devices, and analytics for cloud-based workloads. We need consistent, repeatable methods of architecting, designing, and integrating security for hybrid cloud applications to provide context-based access to resources based on a zero-trust model. However, this is a complex topic that needs to be discussed across various areas for a hybrid multi-cloud infrastructure.

We can look at the benefits of taking a pattern approach to break down this complexity and address the problem context. By specifying right architecture building blocks for the context, we can build reusable solutions as the basis for providing effective security for digital transformation journeys.

In the next chapter, we will learn how to work with patterns better, how to use them, when, why, and what trade-offs to consider. We will cover the security architecture, domains, roles, and responsibilities that we need to know.
