The IDs of vSwitches.

The ECS instance scaling policy for the multi-zone scaling group. Valid values:

• PRIORITY: ECS instances are scaled based on the VSwitchIds.N parameter. If an ECS instance cannot be created in the zone in which the vSwitch that has the highest priority resides, Auto Scaling creates the ECS instance in the zone in which the vSwitch that has the next highest priority resides.

• COST_OPTIMIZED: ECS instances are created based on the vCPU unit price in ascending order. Preemptible instances are preferably created if preemptible instance types are specified in the scaling configurations. You can set CompensateWithOnDemand to specify whether to automatically create pay-as-you-go instances when preemptible instances cannot be created due to insufficient inventory.

  **

  Note COST_OPTIMIZED is valid only when multiple instance types are specified or at least one preemptible instance type is specified.

• BALANCE: ECS instances are evenly distributed across multiple zones specified by the scaling group. If the distribution of ECS instances across zones is not balanced due to reasons such as insufficient inventory, you can call the RebalanceInstances operation to evenly distribute the ECS instances across zones. For more information, see RebalanceInstances

Default value: PRIORITY.

The minimum number of pay-as-you-go instances that must be kept in the scaling group. Valid values: 0 to 1000. If the number of pay-as-you-go instances is smaller than the value of this parameter, Auto Scaling preferably creates pay-as-you-go instances.

• true: supplements preemptible instances.
• false: does not supplement preemptible instances.

Specifies whether to automatically create pay-as-you-go instances to meet the required number of ECS instances if preemptible instances cannot be created due to reasons such as cost or insufficient inventory. This parameter takes effect if you set multi_az_policy to COST_OPTIMIZED. Valid values:
