Azure Stack enables you to run Azure workloads on-premises or even within a colocation facility, enabling stronger security and control over your data and applications with a single management platform for your public Azure cloud infrastructure and your Azure Stack deployment.You can migrate on-premises VMware VMs, Hyper-V VMs, and physical servers to Azure. To do this, you complete almost the same steps as you would for full disaster recovery. You simply don't fail machines back from Azure to the on-premises site.
