    - capacityRebalance
```
Boolean capacityRebalance
```
      Indicates whether Capacity Rebalancing is enabled. Otherwise, Capacity Rebalancing is disabled. When you turn on Capacity Rebalancing, Amazon EC2 Auto Scaling attempts to launch a Spot Instance whenever Amazon EC2 notifies that a Spot Instance is at an elevated risk of interruption. After launching a new instance, it then terminates an old instance. For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the in the Amazon EC2 Auto Scaling User Guide.

      The unit of measurement for the value specified for desired capacity. Amazon EC2 Auto Scaling supports DesiredCapacityType for attribute-based instance type selection only. For more information, see Creating an Auto Scaling group using attribute-based instance type selection in the Amazon EC2 Auto Scaling User Guide.
      
      By default, Amazon EC2 Auto Scaling specifies units, which translates into number of instances.
      
      Valid values: units | vcpu | memory-mib
    - defaultInstanceWarmup
```
Integer defaultInstanceWarmup
```
      The amount of time, in seconds, until a new instance is considered to have finished initializing and resource consumption to become stable after it enters the InService state.
      
      During an instance refresh, Amazon EC2 Auto Scaling waits for the warm-up period after it replaces an instance before it moves on to replacing the next instance. Amazon EC2 Auto Scaling also waits for the warm-up period before aggregating the metrics for new instances with existing instances in the Amazon CloudWatch metrics that are used for scaling, resulting in more reliable usage data. For more information, see Set the default instance warmup for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.
      
      To manage various warm-up settings at the group level, we recommend that you set the default instance warmup, even if it is set to 0 seconds. To remove a value that you previously set, include the property but specify -1 for the value. However, we strongly recommend keeping the default instance warmup enabled by specifying a value of 0 or other nominal value.
      
      Default: None

    - instanceId
```
String instanceId
```
      The ID of the instance to use to create the launch configuration. The new launch configuration derives attributes from the instance, except for the block device mapping.
      
      To create a launch configuration with a block device mapping or override any other instance attributes, specify them as part of the same request.
      
      For more information, see Creating a launch configuration using an EC2 instance in the Amazon EC2 Auto Scaling User Guide.

      Controls whether instances in this group are launched with detailed (true) or basic ( false) monitoring.
      
      The default value is true (enabled).
      
      When detailed monitoring is enabled, Amazon CloudWatch generates metrics every minute and your account is charged a fee. When you disable detailed monitoring, CloudWatch generates metrics every 5 minutes. For more information, see Configure Monitoring for Auto Scaling Instances in the Amazon EC2 Auto Scaling User Guide.
    - spotPrice

For more information, see Request Spot Instances for fault-tolerant and flexible applications in the Amazon EC2 Auto Scaling User Guide.
      
      Valid Range: Minimum value of 0.001
      
      When you change your maximum price by creating a new launch configuration, running instances will continue to run as long as the maximum price for those running instances is higher than the current Spot price.
    - iamInstanceProfile
```
String iamInstanceProfile
```

    - ebsOptimized
```
Boolean ebsOptimized
```
      Specifies whether the launch configuration is optimized for EBS I/O (true) or not ( false). The optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization is not available with all instance types. Additional fees are incurred when you enable EBS optimization for an instance type that is not EBS-optimized by default. For more information, see Amazon EBS-optimized instances in the Amazon EC2 User Guide for Linux Instances.
      
      The default value is false.
    - associatePublicIpAddress
```
Boolean associatePublicIpAddress
```
      Specifies whether to assign a public IPv4 address to the group's instances. If the instance is launched into a default subnet, the default is to assign a public IPv4 address, unless you disabled the option to assign a public IPv4 address on the subnet. If the instance is launched into a nondefault subnet, the default is not to assign a public IPv4 address, unless you enabled the option to assign a public IPv4 address on the subnet.
      
      If you specify true, each instance in the Auto Scaling group receives a unique public IPv4 address. For more information, see Launching Auto Scaling instances in a VPC in the Amazon EC2 Auto Scaling User Guide.
      
      If you specify this property, you must specify at least one subnet for VPCZoneIdentifier when you create your group.
    - placementTenancy
```
String 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. For more information, see Configuring instance tenancy with Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.
      
      If you specify PlacementTenancy, you must specify at least one subnet for VPCZoneIdentifier when you create your group.
      
      Valid values: default | dedicated
    - metadataOptions
```
InstanceMetadataOptions metadataOptions
```

      Valid values: standard | io1 | gp2 | st1 | sc1 | gp3
    - deleteOnTermination
```
Boolean deleteOnTermination
```
      Indicates whether the volume is deleted on instance termination. For Amazon EC2 Auto Scaling, the default value is true.
    - iops
```
Integer iops
```
      The number of input/output (I/O) operations per second (IOPS) to provision for the volume. For gp3 and io1 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
      
      The following are the supported values for each volume type:
      
      gp3: 3,000-16,000 IOPS
      
      io1: 100-64,000 IOPS
      
      For io1 volumes, we guarantee 64,000 IOPS only for Instances built on the Nitro System. Other instance families guarantee performance up to 32,000 IOPS.
      
      Iops is supported when the volume type is gp3 or io1 and required only when the volume type is io1. (Not used with standard, gp2, st1, or sc1 volumes.)
    - encrypted
```
Boolean encrypted
```
      Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types. If your AMI uses encrypted volumes, you can also only launch it on supported instance types.
      
      If you are creating a volume from a snapshot, you cannot create an unencrypted volume from an encrypted snapshot. Also, you cannot specify a KMS key ID when using a launch configuration.
      
      If you enable encryption by default, the EBS volumes that you create are always encrypted, either using the Amazon Web Services managed KMS key or a customer-managed KMS key, regardless of whether the snapshot was encrypted.
      
      For more information, see Use Amazon Web Services KMS keys to encrypt Amazon EBS volumes in the Amazon EC2 Auto Scaling User Guide.

      The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.
      
      If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.
      
      If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.
    - httpPutResponseHopLimit
```
Integer httpPutResponseHopLimit
```
      The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.
      
      Default: 1
    - httpEndpoint
```
String httpEndpoint
```
      This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled.
      
      If you specify a value of disabled, you will not be able to access your instance metadata.

    - spotMaxPricePercentageOverLowestPrice
```
Integer spotMaxPricePercentageOverLowestPrice
```
      [Price protection] The price protection threshold for Spot Instances, as a percentage higher than an identified Spot price. The identified Spot price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified price is from either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold.
      
      The parameter accepts an integer, which Amazon EC2 Auto Scaling interprets as a percentage.
      
      If you set DesiredCapacityType to vcpu or memory-mib, the price protection threshold is based on the per-vCPU or per-memory price instead of the per instance price.
      
      Only one of SpotMaxPricePercentageOverLowestPrice or MaxSpotPriceAsPercentageOfOptimalOnDemandPrice can be specified. If you don't specify either, Amazon EC2 Auto Scaling will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as 999999.
    - maxSpotPriceAsPercentageOfOptimalOnDemandPrice

    - onDemandAllocationStrategy
```
String onDemandAllocationStrategy
```
      The allocation strategy to apply to your On-Demand Instances when they are launched. Possible instance types are determined by the launch template overrides that you specify.
      
      The following lists the valid values:
      
      lowest-price
      
      Uses price to determine which instance types are the highest priority, launching the lowest priced instance types within an Availability Zone first. This is the default value for Auto Scaling groups that specify InstanceRequirements.
      
      prioritized
      
      You set the order of instance types for the launch template overrides from highest to lowest priority (from first to last in the list). Amazon EC2 Auto Scaling launches your highest priority instance types first. If all your On-Demand capacity cannot be fulfilled using your highest priority instance type, then Amazon EC2 Auto Scaling launches the remaining capacity using the second priority instance type, and so on. This is the default value for Auto Scaling groups that don't specify InstanceRequirements and cannot be used for groups that do.
    - onDemandBaseCapacity
```
Integer onDemandBaseCapacity
```
      The minimum amount of the Auto Scaling group's capacity that must be fulfilled by On-Demand Instances. This base portion is launched first as your group scales.
      
      This number has the same unit of measurement as the group's desired capacity. If you change the default unit of measurement (number of instances) by specifying weighted capacity values in your launch template overrides list, or by changing the default desired capacity type setting of the group, you must specify this number using the same unit of measurement.
      
      Default: 0
    - onDemandPercentageAboveBaseCapacity
```
Integer onDemandPercentageAboveBaseCapacity
```
      Controls the percentages of On-Demand Instances and Spot Instances for your additional capacity beyond OnDemandBaseCapacity. Expressed as a number (for example, 20 specifies 20% On-Demand Instances, 80% Spot Instances). If set to 100, only On-Demand Instances are used.
      
      Default: 100
    - spotAllocationStrategy
```
String spotAllocationStrategy
```
      The allocation strategy to apply to your Spot Instances when they are launched. Possible instance types are determined by the launch template overrides that you specify.
      
      The following lists the valid values:
      
      capacity-optimized
      
      Requests Spot Instances using pools that are optimally chosen based on the available Spot capacity. This strategy has the lowest risk of interruption. To give certain instance types a higher chance of launching first, use capacity-optimized-prioritized.
      
      capacity-optimized-prioritized
      
      You set the order of instance types for the launch template overrides from highest to lowest priority (from first to last in the list). Amazon EC2 Auto Scaling honors the instance type priorities on a best effort basis but optimizes for capacity first. Note that if the On-Demand allocation strategy is set to prioritized, the same priority is applied when fulfilling On-Demand capacity. This is not a valid value for Auto Scaling groups that specify InstanceRequirements.
      
      lowest-price
      
      Requests Spot Instances using the lowest priced pools within an Availability Zone, across the number of Spot pools that you specify for the SpotInstancePools property. To ensure that your desired capacity is met, you might receive Spot Instances from several pools. This is the default value, but it might lead to high interruption rates because this strategy only considers instance price and not available capacity.
      
      price-capacity-optimized (recommended)
      
      The price and capacity optimized allocation strategy looks at both price and capacity to select the Spot Instance pools that are the least likely to be interrupted and have the lowest possible price.
    - spotInstancePools
```
Integer spotInstancePools
```
      The number of Spot Instance pools across which to allocate your Spot Instances. The Spot pools are determined from the different instance types in the overrides. Valid only when the SpotAllocationStrategy is lowest-price. Value must be in the range of 1–20.
      
      Default: 2
    - spotMaxPrice
```
String spotMaxPrice
```
      The maximum price per unit hour that you are willing to pay for a Spot Instance. If your maximum price is lower than the Spot price for the instance types that you selected, your Spot Instances are not launched. We do not recommend specifying a maximum price because it can lead to increased interruptions. When Spot Instances launch, you pay the current Spot price. To remove a maximum price that you previously set, include the property but specify an empty string ("") for the value.
      
      If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify one.
      
      Valid Range: Minimum value of 0.001

    - instanceType
```
String instanceType
```
      The instance type, such as m3.xlarge. You must specify an instance type that is supported in your requested Region and Availability Zones. For more information, see Instance types in the Amazon Elastic Compute Cloud User Guide.
      
      You can specify up to 40 instance types per Auto Scaling group.
    - weightedCapacity
```
String weightedCapacity
```
      If you provide a list of instance types to use, you can specify the number of capacity units provided by each instance type in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic. When a Spot or On-Demand Instance is launched, the capacity units count toward the desired capacity. Amazon EC2 Auto Scaling launches instances until the desired capacity is totally fulfilled, even if this results in an overage. For example, if there are two units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only launch an instance with a WeightedCapacity of five units, the instance is launched, and the desired capacity is exceeded by three units. For more information, see Configuring instance weighting for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide. Value must be in the range of 1–999.
      
      If you specify a value for WeightedCapacity for one instance type, you must specify a value for WeightedCapacity for all of them.
      
      Every Auto Scaling group has three size parameters (DesiredCapacity, MaxSize, and MinSize). Usually, you set these sizes based on a specific number of instances. However, if you configure a mixed instances policy that defines weights for the instance types, you must specify these sizes with the same units that you use for weighting instances.
    - launchTemplateSpecification
```
LaunchTemplateSpecification launchTemplateSpecification
```
      Provides a launch template for the specified instance type or set of instance requirements. For example, some instance types might require a launch template with a different AMI. If not provided, Amazon EC2 Auto Scaling uses the launch template that's specified in the LaunchTemplate definition. For more information, see Specifying a different launch template for an instance type in the Amazon EC2 Auto Scaling User Guide.
      
      You can specify up to 20 launch templates per Auto Scaling group. The launch templates specified in the overrides and in the LaunchTemplate definition count towards this limit.
    - instanceRequirements
```
InstanceRequirements instanceRequirements
```
      The instance requirements. Amazon EC2 Auto Scaling uses your specified requirements to identify instance types. Then, it uses your On-Demand and Spot allocation strategies to launch instances from these instance types.
      
      You can specify up to four separate sets of instance requirements per Auto Scaling group. This is useful for provisioning instances from different Amazon Machine Images (AMIs) in the same Auto Scaling group. To do this, create the AMIs and create a new launch template for each AMI. Then, create a compatible set of instance requirements for each launch template.
      
      If you specify InstanceRequirements, you can't specify InstanceType.

    - mode
```
String mode
```
      The predictive scaling mode. Defaults to ForecastOnly if not specified.
    - schedulingBufferTime
```
Integer schedulingBufferTime
```
      The amount of time, in seconds, by which the instance launch time can be advanced. For example, the forecast says to add capacity at 10:00 AM, and you choose to pre-launch instances by 5 minutes. In that case, the instances will be launched at 9:55 AM. The intention is to give resources time to be provisioned. It can take a few minutes to launch an EC2 instance. The actual amount of time required depends on several factors, such as the size of the instance and whether there are startup scripts to complete.
      
      The value must be less than the forecast interval duration of 3600 seconds (60 minutes). Defaults to 300 seconds if not specified.
    - maxCapacityBreachBehavior
```
String maxCapacityBreachBehavior
```
      Defines the behavior that should be applied if the forecast capacity approaches or exceeds the maximum capacity of the Auto Scaling group. Defaults to HonorMaxCapacity if not specified.
      
      The following are possible values:
      
      HonorMaxCapacity - Amazon EC2 Auto Scaling cannot scale out capacity higher than the maximum capacity. The maximum capacity is enforced as a hard limit.
      
      IncreaseMaxCapacity - Amazon EC2 Auto Scaling can scale out capacity higher than the maximum capacity when the forecast capacity is close to or exceeds the maximum capacity. The upper limit is determined by the forecasted capacity and the value for MaxCapacityBuffer.
    - maxCapacityBuffer
```
Integer maxCapacityBuffer
```
      The size of the capacity buffer to use when the forecast capacity is close to or exceeds the maximum capacity. The value is specified as a percentage relative to the forecast capacity. For example, if the buffer is 10, this means a 10 percent buffer, such that if the forecast capacity is 50, and the maximum capacity is 40, then the effective maximum capacity is 55.
      
      If set to 0, Amazon EC2 Auto Scaling may scale capacity higher than the maximum capacity to equal but not exceed forecast capacity.
      
      Required if the MaxCapacityBreachBehavior property is set to IncreaseMaxCapacity, and cannot be used otherwise.

      The metric type.
    - resourceLabel
```
String resourceLabel
```
      A label that uniquely identifies a specific Application Load Balancer target group from which to determine the average request count served by your Auto Scaling group. You can't specify a resource label unless the target group is attached to the Auto Scaling group.
      
      You create the resource label by appending the final portion of the load balancer ARN and the final portion of the target group ARN into a single value, separated by a forward slash (/). The format of the resource label is:

```
      Available for backward compatibility. Use MinAdjustmentMagnitude instead.
    - minAdjustmentMagnitude
```
Integer minAdjustmentMagnitude
```
      The minimum value to scale by when the adjustment type is PercentChangeInCapacity. For example, suppose that you create a step scaling policy to scale out an Auto Scaling group by 25 percent and you specify a MinAdjustmentMagnitude of 2. If the group has 4 instances and the scaling policy is performed, 25 percent of 4 is 1. However, because you specified a MinAdjustmentMagnitude of 2, Amazon EC2 Auto Scaling scales out the group by 2 instances.
      
      Valid only if the policy type is StepScaling or SimpleScaling. For more information, see Scaling adjustment types in the Amazon EC2 Auto Scaling User Guide.
      
      Some Auto Scaling groups use instance weights. In this case, set the MinAdjustmentMagnitude to a value that is at least as large as your largest instance weight.
    - scalingAdjustment
```
Integer scalingAdjustment
```
      The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity. For exact capacity, you must specify a non-negative value.
      
      Required if the policy type is SimpleScaling. (Not used with any other policy type.)
    - cooldown
```
Integer cooldown
```
      A cooldown period, in seconds, that applies to a specific simple scaling policy. When a cooldown period is specified here, it overrides the default cooldown.
      
      Valid only if the policy type is SimpleScaling. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.
      
      Default: None
    - metricAggregationType
```
String metricAggregationType
```
      The aggregation type for the CloudWatch metrics. The valid values are Minimum, Maximum, and Average. If the aggregation type is null, the value is treated as Average.
      
      Valid only if the policy type is StepScaling.

```
Integer estimatedInstanceWarmup
```
      Not needed if the default instance warmup is defined for the group.
      
      The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This warm-up period applies to instances launched due to a specific target tracking or step scaling policy. When a warm-up period is specified here, it overrides the default instance warmup.
      
      Valid only if the policy type is TargetTrackingScaling or StepScaling.
      
      The default is to use the value for the default instance warmup defined for the group. If default instance warmup is null, then EstimatedInstanceWarmup falls back to the value of default cooldown.
    - targetTrackingConfiguration
```
TargetTrackingConfiguration targetTrackingConfiguration
```
      A target tracking scaling policy. Provides support for predefined or custom metrics.

      You must specify at least one of the following properties: MaxSize, MinSize, or DesiredCapacity.
    - timeZone
```
String timeZone
```
      Specifies the time zone for a cron expression. If a time zone is not provided, UTC is used by default.
      
      Valid values are the canonical names of the IANA time zones, derived from the IANA Time Zone Database (such as Etc/GMT+9 or Pacific/Tahiti). For more information, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones.

    - maxGroupPreparedCapacity
```
Integer maxGroupPreparedCapacity
```
      Specifies the maximum number of instances that are allowed to be in the warm pool or in any state except Terminated for the Auto Scaling group. This is an optional property. Specify it only if you do not want the warm pool size to be determined by the difference between the group's maximum capacity and its desired capacity.
      
      If a value for MaxGroupPreparedCapacity is not specified, Amazon EC2 Auto Scaling launches and maintains the difference between the group's maximum capacity and its desired capacity. If you specify a value for MaxGroupPreparedCapacity, Amazon EC2 Auto Scaling uses the difference between the MaxGroupPreparedCapacity and the desired capacity instead.
      
      The size of the warm pool is dynamic. Only when MaxGroupPreparedCapacity and MinSize are set to the same value does the warm pool have an absolute size.
      
      If the desired capacity of the Auto Scaling group is higher than the MaxGroupPreparedCapacity, the capacity of the warm pool is 0, unless you specify a value for MinSize. To remove a value that you previously set, include the property but specify -1 for the value.
    - minSize
```
Integer minSize
```
      Specifies the minimum number of instances to maintain in the warm pool. This helps you to ensure that there is always a certain number of warmed instances available to handle traffic spikes. Defaults to 0 if not specified.

```
String poolState
```
      Sets the instance state to transition to after the lifecycle actions are complete. Default is Stopped.
    - instanceReusePolicy
```

    - minHealthyPercentage
```
Integer minHealthyPercentage
```
      Specifies the minimum percentage of the group to keep in service, healthy, and ready to use to support your workload to allow the operation to continue. The value is expressed as a percentage of the desired capacity of the Auto Scaling group. Value range is 0 to 100.
      
      If you do not specify this property, the default is 90 percent, or the percentage set in the instance maintenance policy for the Auto Scaling group, if defined.
    - instanceWarmup
```
Integer instanceWarmup
```
      A time period, in seconds, during which an instance refresh waits before moving on to replacing the next instance after a new instance enters the InService state.
      
      This property is not required for normal usage. Instead, use the DefaultInstanceWarmup property of the Auto Scaling group. The InstanceWarmup and DefaultInstanceWarmup properties work the same way. Only specify this property if you must override the DefaultInstanceWarmup property.
      
      If you do not specify this property, the instance warmup by default is the value of the DefaultInstanceWarmup property, if defined (which is recommended in all cases), or the HealthCheckGracePeriod property otherwise.
    - checkpointPercentages
```
SdkInternalList<T> checkpointPercentages
```
      (Optional) Threshold values for each checkpoint in ascending order. Each number must be unique. To replace all instances in the Auto Scaling group, the last number in the array must be 100.

    - checkpointDelay
```
Integer checkpointDelay
```
      (Optional) The amount of time, in seconds, to wait after a checkpoint before continuing. This property is optional, but if you specify a value for it, you must also specify a value for CheckpointPercentages . If you specify a value for CheckpointPercentages and not for CheckpointDelay, the CheckpointDelay defaults to 3600 (1 hour).
    - skipMatching
```
Boolean skipMatching
```
      (Optional) Indicates whether skip matching is enabled. If enabled (true), then Amazon EC2 Auto Scaling skips replacing instances that match the desired configuration. If no desired configuration is specified, then it skips replacing instances that have the same launch template and instance types that the Auto Scaling group was using before the start of the instance refresh. The default is false.
      
      For more information, see Use an instance refresh with skip matching in the Amazon EC2 Auto Scaling User Guide.
    - autoRollback
```
Boolean autoRollback
```
      (Optional) Indicates whether to roll back the Auto Scaling group to its previous configuration if the instance refresh fails or a CloudWatch alarm threshold is met. The default is false.
      
      A rollback is not supported in the following situations:
      
      There is no desired configuration specified for the instance refresh.
      
      The Auto Scaling group has a launch template that uses an Amazon Web Services Systems Manager parameter instead of an AMI ID for the ImageId property.
      
      The Auto Scaling group uses the launch template's $Latest or $Default version.
      
      For more information, see Undo changes with a rollback in the Amazon EC2 Auto Scaling User Guide.

      Wait (default)
      
      Amazon EC2 Auto Scaling waits one hour for you to remove scale-in protection. Otherwise, the instance refresh will fail.
    - standbyInstances
```
String standbyInstances
```
      Choose the behavior that you want Amazon EC2 Auto Scaling to use if instances in Standby state are found.
      
      The following lists the valid values:

      Amazon EC2 Auto Scaling terminates instances that are in Standby.
      
      Ignore
      
      Amazon EC2 Auto Scaling ignores instances that are in Standby and continues to replace instances that are in the InService state.
      
      Wait (default)
      
      Amazon EC2 Auto Scaling waits one hour for you to return the instances to service. Otherwise, the instance refresh will fail.
    - alarmSpecification
```
AlarmSpecification alarmSpecification
```
      (Optional) The CloudWatch alarm specification. CloudWatch alarms can be used to identify any issues and fail the operation if an alarm threshold is met.
    - maxHealthyPercentage
```
Integer maxHealthyPercentage
```
      Specifies the maximum percentage of the group that can be in service and healthy, or pending, to support your workload when replacing instances. The value is expressed as a percentage of the desired capacity of the Auto Scaling group. Value range is 100 to 200.
      
      If you specify MaxHealthyPercentage, you must also specify MinHealthyPercentage, and the difference between them cannot be greater than 100. A larger range increases the number of instances that can be replaced at the same time.
      
      If you do not specify this property, the default is 100 percent, or the percentage set in the instance maintenance policy for the Auto Scaling group, if defined.

      The amount of time, in seconds, until a new instance is considered to have finished initializing and resource consumption to become stable after it enters the InService state.
      
      During an instance refresh, Amazon EC2 Auto Scaling waits for the warm-up period after it replaces an instance before it moves on to replacing the next instance. Amazon EC2 Auto Scaling also waits for the warm-up period before aggregating the metrics for new instances with existing instances in the Amazon CloudWatch metrics that are used for scaling, resulting in more reliable usage data. For more information, see Set the default instance warmup for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.
      
      To manage various warm-up settings at the group level, we recommend that you set the default instance warmup, even if it is set to 0 seconds. To remove a value that you previously set, include the property but specify -1 for the value. However, we strongly recommend keeping the default instance warmup enabled by specifying a value of 0 or other nominal value.
    - instanceMaintenancePolicy
```
InstanceMaintenancePolicy instanceMaintenancePolicy
```
      An instance maintenance policy. For more information, see Set instance maintenance policy in the Amazon EC2 Auto Scaling User Guide.
