placementTenancy

The tenancy of the instance, either default or dedicated. An instance with dedicated tenancy runs on isolated, single-tenant hardware and can only be launched into a VPC. To launch dedicated instances into a shared tenancy VPC (a VPC with the instance placement tenancy attribute set to default), you must set the value of this property to dedicated.

If you specify PlacementTenancy, you must specify at least one subnet for VPCZoneIdentifier when you create your group.

Valid values: default | dedicated
