Standard quota: Increase limits by VM series

Azure Resource Manager supports two types of vCPU quotas for virtual machines:

  • Pay-as-you-go VMs and reserved VM instances are subject to a standard vCPU quota.
  • Spot VMs are subject to a spot vCPU quota.

The standard vCPU quota for pay-as-you-go and reserved virtual machine instances is enforced at two tiers for each subscription in each region:

  • The first tier is the total regional vCPUs limit, across all VM series.
  • The second tier is the per-VM series vCPUs limit, such as the Dv3-series vCPUs.

Whenever you deploy a new spot VM, the total new and existing vCPU usage for that VM series must not exceed the approved vCPU quota for that particular VM series. Additionally, the total number of new and existing vCPUs that are deployed across all VM series shouldn't exceed the total approved regional vCPU quota for the subscription. If either of these quotas is exceeded, the VM deployment isn't allowed.

You can request an increase in the vCPU quota limit for the VM series by using the Azure portal. An increase in the VM series quota automatically increases the total regional vCPU limit by the same amount.

To learn more about standard vCPU quotas, see Virtual machine vCPU quotas and Azure subscription and service limits.

To learn about increasing the vCPU limit by region for standard quota, see Standard quota: Increase limits by region.

To learn more about increasing spot VM vCPU limits, see Spot quota: Increase limits for all VM series.

You can request an increase in standard vCPU quota limits per VM series in either of two ways, as described in the following sections.
