Azure Arc
A service that extends Azure management and governance to on-premises, multicloud, and edge resources.
Azure Arc extends the Azure control plane to resources outside Azure—including on-premises servers, Kubernetes clusters, and virtual machines in other clouds such as AWS or Google Cloud. By projecting them into Azure Resource Manager, Arc makes them manageable through the Azure portal, Azure Policy, and Microsoft Defender for Cloud, without migrating the workloads. The key exam distinction is management reach, not hosting: Arc governs non-Azure resources but does not run workloads in Azure. Contrast it with Azure Migrate, which actually moves workloads into Azure. Hybrid or multicloud governance scenarios—especially enforcing consistent policy across environments—point to Azure Arc.
