Describes a Virtual Machine Scale Set.

Resource

Properties

additionalCapabilities	Specifies additional capabilities enabled or disabled on the Virtual Machines in the Virtual Machine Scale Set. For instance: whether the Virtual Machines have the capability to support attaching managed data disks with UltraSSD_LRS storage account type.
automaticRepairsPolicy	Policy for automatic repairs.
constrainedMaximumCapacity	Optional property which must either be set to True or omitted.
doNotRunExtensionsOnOverprovisionedVMs	When Overprovision is enabled, extensions are launched only on the requested number of VMs which are finally kept. This property will hence ensure that the extensions do not run on the extra overprovisioned VMs.
etag	Etag is property returned in Create/Update/Get response of the VMSS, so that customer can supply it in the header to ensure optimistic updates NOTE: This property will not be serialized. It can only be populated by the server.
extendedLocation	The extended location of the Virtual Machine Scale Set.
hostGroup	Specifies information about the dedicated host group that the virtual machine scale set resides in. Minimum api-version: 2020-06-01.
identity	The identity of the virtual machine scale set, if configured.
orchestrationMode	Specifies the orchestration mode for the virtual machine scale set.
overprovision	Specifies whether the Virtual Machine Scale Set should be overprovisioned.
plan	Specifies information about the marketplace image used to create the virtual machine. This element is only used for marketplace images. Before you can use a marketplace image from an API, you must enable the image for programmatic use. In the Azure portal, find the marketplace image that you want to use and then click Want to deploy programmatically, Get Started ->. Enter any required information and then click Save.
platformFaultDomainCount	Fault Domain count for each placement group.
priorityMixPolicy	Specifies the desired targets for mixing Spot and Regular priority VMs within the same VMSS Flex instance.
provisioningState	The provisioning state, which only appears in the response. NOTE: This property will not be serialized. It can only be populated by the server.
proximityPlacementGroup	Specifies information about the proximity placement group that the virtual machine scale set should be assigned to. Minimum api-version: 2018-04-01.
resiliencyPolicy	Policy for Resiliency
scaleInPolicy	Specifies the policies applied when scaling in Virtual Machines in the Virtual Machine Scale Set.
singlePlacementGroup	When true this limits the scale set to a single placement group, of max size 100 virtual machines. NOTE: If singlePlacementGroup is true, it may be modified to false. However, if singlePlacementGroup is false, it may not be modified to true.
sku	The virtual machine scale set sku.
spotRestorePolicy	Specifies the Spot Restore properties for the virtual machine scale set.
timeCreated	Specifies the time at which the Virtual Machine Scale Set resource was created. Minimum api-version: 2021-11-01. NOTE: This property will not be serialized. It can only be populated by the server.
uniqueId	Specifies the ID which uniquely identifies a Virtual Machine Scale Set. NOTE: This property will not be serialized. It can only be populated by the server.
upgradePolicy	The upgrade policy.
virtualMachineProfile	The virtual machine profile.
zoneBalance	Whether to force strictly even Virtual Machine distribution cross x-zones in case there is zone outage. zoneBalance property can only be set if the zones property of the scale set contains more than one zone. If there are no zones or only one zone specified, then zoneBalance property should not be set.
zones	The virtual machine scale set zones. NOTE: Availability zones can only be set when you create the scale set

Inherited Properties
