Properties

dedicatedHostType^Required

public readonly dedicatedHostType: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property dedicatedHostType: The dedicated host type.

You can call the DescribeDedicatedHostTypes operation to query the most recent list of dedicated host types.

actionOnMaintenance^Optional

public readonly actionOnMaintenance: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property actionOnMaintenance: The policy for migrating the instances deployed on the dedicated host when the dedicated host fails or needs to be repaired online.

Valid values: - Migrate: The instances are migrated to another physical machine and then restarted. If cloud disks are attached to the dedicated host, the default value is Migrate. - Stop: The instances are stopped. If the dedicated host cannot be repaired, the instances are migrated to another physical machine and then restarted. If local disks are attached to the dedicated host, the default value is Stop.

autoPlacement^Optional

public readonly autoPlacement: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property autoPlacement: Specifies whether the dedicated host is added to the resource pool for automatic deployment.

If you do not specify the DedicatedHostId parameter when you create an instance on a dedicated host, Alibaba Cloud automatically selects a dedicated host from the resource pool to host the instance. For more information, see Automatic deployment. Valid values:on: The dedicated host is added to the resource pool for automatic deployment.off: The dedicated host is not added to the resource pool for automatic deployment.Default value: on.Note When you create a dedicated host: If you do not specify this parameter, the dedicated host is added to the automatic deployment resource pool.If you do not want to add the dedicated host to the automatic deployment resource pool, set the value to off.

autoReleaseTime^Optional

public readonly autoReleaseTime: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property autoReleaseTime: The time when to automatically release the dedicated host.

Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.

• It must be at least half an hour later than the current time.
• It must be at most three years later than the current time.
• If the value of seconds (ss) is not 00, it is automatically set to 00.

autoRenew^Optional

public readonly autoRenew: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property autoRenew: Whether renew the fee automatically?

When the parameter InstanceChargeType is PrePaid, it will take effect. Range of value:True: automatic renewal.False: no automatic renewal. Default value is False.

autoRenewPeriod^Optional

public readonly autoRenewPeriod: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property autoRenewPeriod: The time period of auto renew.

When the parameter InstanceChargeType is PrePaid, it will take effect.It could be 1, 2, 3, 6, 12, 24, 36, 48, 60. Default value is 1.

chargeType^Optional

public readonly chargeType: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property chargeType: Instance Charge type, allowed value: Prepaid and Postpaid.

If specified Prepaid, please ensure you have sufficient balance in your account. Or instance creation will be failure. Default value is Postpaid.

cpuOverCommitRatio^Optional

public readonly cpuOverCommitRatio: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property cpuOverCommitRatio: The CPU overcommit ratio.

You can configure CPU overcommit ratios only for the following dedicated host types: g6s, c6s, and r6s. Valid values: 1 to 5. The CPU overcommit ratio affects the number of available vCPUs on a dedicated host. You can use the following formula to calculate the number of available vCPUs on a dedicated host: Number of available vCPUs = Number of physical CPU cores * 2 * CPU overcommit ratio. For example, the number of physical CPU cores on each g6s dedicated host is 52. If you set the CPU overcommit ratio of a g6s dedicated host to 4, the number of available vCPUs on the dedicated host is 416. For scenarios that have minimal requirements on CPU stability or where CPU load is not heavy, such as development and test environments, you can increase the number of available vCPUs on a dedicated host by increasing the CPU overcommit ratio. This way, you can deploy more ECS instances of the same specifications on the dedicated host and reduce the unit deployment cost.

dedicatedHostClusterId^Optional

public readonly dedicatedHostClusterId: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property dedicatedHostClusterId: The ID of the dedicated host cluster.

dedicatedHostName^Optional

public readonly dedicatedHostName: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property dedicatedHostName: The name of the dedicated host.

The name must be 2 to 128 characters in length and can contain letters and digits. The name can contain colons (:), underscores (_), periods (.), and hyphens (-).

description^Optional

public readonly description: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property description: The description of the dedicated host.

The description must be 2 to 256 characters in length and cannot start with http:\/\/ or https:\/\/.

minQuantity^Optional

public readonly minQuantity: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property minQuantity: The minimum number of dedicated hosts to create.

Valid values: 1 to 100.

If the number of available dedicated hosts is less than the minimum number of dedicated hosts to create, the dedicated hosts fail to be created.
