Azure Kubernetes Service enabled by Azure Arc (AKS Arc) is a managed Kubernetes service that you can use to deploy and manage containerized applications on-premises, in datacenters, or at edge locations. It enables you to use familiar tools such as the Azure portal, Azure CLI, Azure Resource Manager, and Bicep and Terraform templates to create and manage your Kubernetes clusters running on different infrastructure platforms. Microsoft continues to focus on delivering consistent user experience for all your AKS Arc clusters. To continue ensuring Azure remains the best possible experience with the highest standards of safety and reliability, **we are retiring the current architecture of AKS enabled by Azure Arc on all versions of Windows Server - that includes AKS Arc on Windows Server 2019 and on Windows Server 2022, in 3 years, on March 27, 2028**.

AKS Arc deployments on modern Azure Local are now managed entirely through Azure Resource Manager (ARM). This means administrators must use cloud-based tools such as the Azure CLI (az commands), the Azure portal web interface, or Azure Resource Manager templates to perform cluster operations. This architectural shift aligns AKS Arc management with Microsoft's broader cloud-first strategy and ensures consistency across different deployment scenarios, but it requires administrators to adapt their operational procedures and tooling to work with Azure-based management interfaces rather than local ones. This means that local, PowerShell, or Windows Admin Center commands such as `Update-AksHciCluster` that worked on Windows Server don't work on Azure Local.

Additionally, AKS Arc functionality is tightly coupled with having a current, supported version of Azure Local as the underlying infrastructure. This dependency means that organizations cannot simply upgrade AKS Arc independently - they must ensure their Azure Local platform itself is running a supported version to enable proper AKS Arc functionality.
