Azure Stack HCI billing and payment

  • Article

Applies to: Azure Stack HCI, versions 22H2 and 21H2

Azure Stack HCI is an Azure service that goes on your Azure subscription bill just like any other Azure service. It's priced on a per core basis on your on-premises servers. For current pricing, see Azure Stack HCI pricing. Currencies and discounts are handled centrally by the Azure Commerce billing platform, and the customer gets one unified, itemized bill at the end of the month.

No traditional on-premises software license is required for Azure Stack HCI, although guest virtual machines (VMs) may require individual operating system licensing - see Activate Windows Server VMs.

Tip

You can get cost savings with Azure Hybrid Benefit if you have Windows Server Datacenter licenses with active Software Assurance. For more information about Azure Hybrid Benefit, see Azure Hybrid Benefit for Azure Stack HCI.

What does Azure Stack HCI charge for?

Azure Stack HCI's cloud-style billing model is consistent, familiar, and easy for customers already using Azure or any other cloud service. Billing is based on a flat rate per physical processor core in an Azure Stack HCI cluster (additional usage charges apply if you use other Azure services).

The pricing model is different from a usage-based or consumption-based billing that's based on the number of VMs. While the number of virtual processor cores (VCPUs) may vary over the course of the month, it doesn't affect the price you pay for Azure Stack HCI: you still pay based on the number of physical cores that are present in the cluster.

Advantages of the Azure Stack HCI billing model

  • It's simple: There's no minimum, no maximum, and no math with memory, storage, or network ingress/egress.
  • It rewards customers who run their virtualization infrastructure more efficiently, with higher virtual-to-physical density.
  • It's easy to figure out how much your on-premises Azure Stack HCI deployment will cost, and costs scale predictably from the network edge to the data center.

How the number of processor cores is assessed

To determine how many cores are present in a cluster, Azure Stack HCI periodically checks the number of physical cores and reports them to Azure. If you're only occasionally connected or your connection is interrupted, don't worry; it can always try again later. Days or weeks of core data can be uploaded at once. Customers must connect to Azure at least once every 30 days to allow for billing.

To manually upload core data to Azure, use the Sync-AzureStackHCI cmdlet.
