Save costs with reservations for Nutanix Cloud Clusters on Azure BareMetal infrastructure

  • บทความ

You can save money on Nutanix Cloud Clusters (NC2) on Azure with reservations. The reservation discount automatically applies to the running NC2 workload on Azure hosts that match the reservation scope and attributes. A reservation purchase covers only the compute part of your usage and doesn't include software licensing costs.

Purchase restriction considerations

Reservations for NC2 on Azure BareMetal Infrastructure are available with some exceptions.

  • Clouds - Reservations are available only in the regions listed on the Supported regions page.
  • Capacity restrictions - In rare circumstances, Azure limits the purchase of new reservations for NC2 on Azure host SKUs because of low capacity in a region.

Reservation scope

When you purchase a reservation, you choose a scope that determines which resources get the reservation discount. A reservation applies to your usage within the purchased scope.

To choose a subscription scope, use the Scope list at the time of purchase. You can change the reservation scope after purchase.

  • Single resource group scope - Applies the reservation discount to the matching resources in the selected resource group only.
  • Single subscription scope - Applies the reservation discount to the matching resources in the selected subscription.
  • Shared scope - Applies the reservation discount to matching resources in eligible subscriptions that are in the billing context. If a subscription is moved to different billing context, the benefit no longer applies to the subscription. It continues to apply to other subscriptions in the billing context.
    • For enterprise customers, the billing context is the EA enrollment. The reservation shared scope would include multiple Microsoft Entra tenants in an enrollment.
    • For Microsoft Customer Agreement customers, the billing scope is the billing profile.
    • For pay-as-you-go customers, the shared scope is all pay-as-you-go subscriptions created by the account administrator.
  • Management group - Applies the reservation discount to the matching resource in the list of subscriptions that are a part of both the management group and billing scope. The management group scope applies to all subscriptions throughout the entire management group hierarchy. To buy a reservation for a management group, you must have at least read permission on the management group and be a reservation owner or reservation purchaser on the billing subscription.
