Implementing Hybrid Cloud with Azure Arc

Overview of this book

With all the options available for deploying infrastructure on multi-cloud platforms and on-premises comes the complexity of managing it, which is adeptly handled by Azure Arc. This book will show you how you can manage environments across platforms without having to migrate workloads from on-premises or multi-cloud to Azure every time. Implementing Hybrid Cloud with Azure Arc starts with an introduction to Azure Arc and hybrid cloud computing, covering use cases and various supported topologies. You'll learn to set up Windows and Linux servers as Arc-enabled machines and get to grips with deploying applications on Kubernetes clusters with Azure Arc and GitOps. The book then demonstrates how to onboard an on-premises SQL Server infrastructure as an Arc-enabled SQL Server and deploy and manage a hyperscale PostgreSQL infrastructure on-premises through Azure Arc. Along with deployment, the book also covers security, backup, migration, and data distribution aspects. Finally, it shows you how to deploy and manage Azure's data services on your own private cloud and explore multi-cloud solutions with Azure Arc. By the end of this book, you'll have a firm understanding of Azure Arc and how it interacts with various cutting-edge technologies such as Kubernetes and PaaS data services.

Governing connected Kubernetes clusters with Azure Policy

Azure Policy for connected Kubernetes clusters allows you to extend your governance policies to Kubernetes clusters outside Azure. Azure Policy can help you govern your cluster effectively by having the same state across environments and keep a compliance status against all required configurations.

Azure includes a variety of built-in policy templates for Arc enabled Kubernetes clusters; however, you can author your own policies easily using the Custom Policies functionality. Some of the examples include deploying Microsoft defender agents for your cluster nodes or a validation to ensure that the Kubernetes cluster shouldn't allow privileged containers. Please refer to Microsoft documentation (https://docs.microsoft.com/en-us/azure/azure-arc/kubernetes/policy-reference) to learn more about the built-in policy templates available for connected Kubernetes clusters.

In the last example, we leveraged the Azure CLI...
