Spot VMs provide a different model of Azure usage, trading a lower cost for letting Azure remove a VM as needed for Pay-as-you-go or Reserved VM Instance deployments. Read more about Spot VMs[here](https://docs.microsoft.com/azure/virtual-machine-scale-sets/use-spot).

Spot virtual machines (VMs) provide a different model of Azure usage. They let you assume lower costs in exchange for letting Azure remove VMs as needed for pay-as-you-go or reserved VM instance deployments. For more information about spot VMs, see [Azure spot VMs for virtual machine scale sets](https://docs.microsoft.com/azure/virtual-machine-scale-sets/use-spot).

Resource Manager supports two types of vCPU quotas for virtual machines. **Pay-as-you-go VMs and Reserved VM Instances** use standard quota. **Spot VMs** use Spot quota.

Azure Resource Manager supports two types of vCPU quotas for virtual machines:
17
+
**Pay-as-you-go VMs* and *reserved VM instances* are subject to a *standard vCPU quota*.
18
+
**Spot VMs* are subject to a *spot vCPU quota*.

For **Spot quota** type, Resource Manager vCPU quotas are enforced across all available VM Series as a single regional limit.

For the *spot vCPU quota* type, Resource Manager vCPU quotas are enforced across all available VM series as a single regional limit.

Anytime a new Spot VM is to be deployed, the sum of new and existing vCPUs usage for all Spot VM instances must not exceed the approved Spot vCPU quota limit. If the Spot quota is exceeded, the Spot VM deployment will not be allowed. You can request an increase of the Spot vCPUs quota limit from Azure portal.
22

Whenever you deploy a new spot VM, the total new and existing vCPU usage for all spot VM instances must not exceed the approved spot vCPU quota limit. If the spot quota is exceeded, the spot VM deployment isn't allowed.
