What this book covers
Chapter 1, Introducing the New Operating Model, discusses how, for many people, Kubernetes is all about container orchestration. But Kubernetes is much more than that. Understanding the deciding factors on why Kubernetes disrupted the day 1 and day 2 IT operations is key to successful adoption and optimum usage.
Chapter 2, Examining the State of Infrastructure Automation, exposes the limitations of infrastructure as code and proposes control plane-based infrastructure automation as the new-age automation concept using Crossplane and Kubernetes.
Chapter 3, Automating Infrastructure with Crossplane, helps us to understand how to set up a Crossplane cluster, discusses its architecture, and explains how to use it as a vanilla flavor for infrastructure automation.
Chapter 4, Composing Infrastructure with Crossplane, helps us to understand composing, a powerful construct of Crossplane that can help us to create new infrastructure abstractions. These abstractions can be our custom Kubernetes-based cloud APIs with the organization policies, compliance requirements, and recipes baked into them.
Chapter 5, Exploring Infrastructure Platform Patterns, looks at how the success of running an infrastructure platform product within an organization requires a few key patterns that we can use with Crossplane. This chapter will explore these patterns in detail.
Chapter 6, More Crossplane Patterns, explores more Crossplane patterns that are useful for our day-to-day work. We will learn about most of these patterns with a hands-on journey.
Chapter 7, Extending and Scaling Crossplane, covers two unique aspects that make Crossplane extendable and scalable. The first part will deep dive into the Crossplane providers, and the second part will cover how Crossplane can work in a multi-tenant ecosystem.
Chapter 8, Knowing the Trade-Offs, discusses how managing configuration has many nuances to it. Understanding the configuration clock will help us to categorize tools and understand the trade-offs applicable for each category.
Chapter 9, Using Helm, Kustomize, and KubeVela, concentrates on explaining how to use different configuration management tools that are popular today, such as Helm, Kustomize, and KubeVela.
Chapter 10, Onboarding Applications with Crossplane, looks at how infrastructure provisioning and application onboarding involve a few cross-cutting concerns, such as setting up the source code repositories, the continuous integration workflow, and continuous deployment. This chapter will look at ways to approach application, services, and infrastructure automation with Crossplane in a unified way.
Chapter 11, Driving the Platform Adoption, explains that many organizations fail with their technology platform projects because they don’t apply the needed product development practices and team topology. This chapter aims to help understand the aspects required to build and adopt a successful infrastructure platform.
