At MS Build 2022 the Azure Stack HCI Single Node Cluster Announcement has been done.
Azure Stack HCI running on a single-node cluster behaves very similarly to Azure Stack HCI on a multi-node cluster: it brings native Azure Arc integration, you can add servers to scale out the cluster, and it includes the same Azure benefits. It also supports the same workloads, such as Azure Virtual Desktop (AVD) and Azure Kubernetes Service (AKS) on Azure Stack HCI, and lastly it is supported and billed the same way. To learn more, see Using Azure Stack HCI on a single server.
At this time you cannot install a single cluster with Windows Admin Center.
Therefore, I have collected the Powershell scripts for the deployment on my Github page.
