 # Azure Kubernetes Service on Azure Stack Hub overview for users

 Azure Kubernetes Service (AKS) makes it easy to deploy a Kubernetes cluster in Azure and Azure Stack Hub. AKS reduces the complexity and operational overhead of managing Kubernetes clusters.
 
 As a managed Kubernetes service, Azure Stack Hub handles critical tasks such as health monitoring, and facilitates maintenance for you. The Azure Stack Hub team manages the image used for maintaining the clusters. The cluster administrator only needs to apply the updates as needed. The services come at no extra cost. AKS is free; you only pay to use the VMs (master and agent nodes) within your clusters. It's simpler to use than the [AKS engine](azure-stack-kubernetes-aks-engine-overview.md) since it removes some of the manual tasks required with the AKS engine.
 
-> [!IMPORTANT]
-> Azure Kubernetes Service on Azure Stack Hub, currently in preview, is being discontinued and will not become GA. See [AKS Engine](../user/azure-stack-kubernetes-aks-engine-overview.md) for a Kubernetes solution on Azure Stack Hub.

 ## AKS on Azure Stack Hub
 
 You can manage AKS clusters on Azure Stack Hub in the same way you do on the Azure cloud using the same Azure CLI, Azure Stack Hub user portal, Azure Resource Manager templates, and REST API. When you deploy an AKS cluster, the Kubernetes master and all nodes are deployed and configured for you.

 ## Differences between Azure and Azure Stack Hub
 
-AKS on Azure and on Azure Stack Hubs share the same source repository. There are no conceptual differences between the two. However, operating in different environments brings along differences to keep in mind when using AKS on Azure Stack Hub. Most of the differences are related to the system residing inside customers' Data Centers and related to functionality that is not yet available in Azure Stack Hub.

-Often, Azure Stack Hub AKS falls behind Azure in the versions supported for Kubernetes and AKS API. This is due to the difficulties of shipping code for customers to run in their own datacenters.

 This article explains how to migrate existing workloads in the Azure Kubernetes Service (AKS) preview on Azure Stack Hub to AKS engine, and summarizes AKS feature differences. The AKS preview is being deprecated in favor of extending support for AKS engine on Azure Stack Hub.
 
 [AKS engine](https://github.com/Azure/aks-engine) provides a command-line tool to bootstrap Kubernetes clusters on Azure and Azure Stack Hub. By using Azure Resource Manager, AKS engine helps you create and maintain clusters running on VMs, virtual networks, and other Azure infrastructure as a service (IaaS) resources in Azure Stack Hub. To learn more about AKS engine, see the [AKS engine overview](azure-stack-kubernetes-aks-engine-overview.md), and review the [AKS engine feature comparison](#compare-features-aks-engine-vs-aks-preview) in this article.
