        public final String autoScalingGroupName()

        The name of the Auto Scaling group.

        Returns:
        The name of the Auto Scaling group.
      • launchConfigurationName

        public final String launchConfigurationName()

        The name of the launch configuration. If you specify LaunchConfigurationName in your update request, you can't specify LaunchTemplate or MixedInstancesPolicy.

        Returns:
        The name of the launch configuration. If you specify LaunchConfigurationName in your update request, you can't specify LaunchTemplate or MixedInstancesPolicy.
      • launchTemplate

        public final LaunchTemplateSpecification launchTemplate()

        The launch template and version to use to specify the updates. If you specify LaunchTemplate in your update request, you can't specify LaunchConfigurationName or MixedInstancesPolicy.

        Returns:
        The launch template and version to use to specify the updates. If you specify LaunchTemplate in your update request, you can't specify LaunchConfigurationName or MixedInstancesPolicy.
      • minSize

        public final Integer minSize()

        The minimum size of the Auto Scaling group.

        Returns:
        The minimum size of the Auto Scaling group.
      • maxSize

        public final Integer maxSize()

        The maximum size of the Auto Scaling group.

        With a mixed instances policy that uses instance weighting, Amazon EC2 Auto Scaling may need to go above MaxSize to meet your capacity requirements. In this event, Amazon EC2 Auto Scaling will never go above MaxSize by more than your largest instance weight (weights that define how many units each instance contributes to the desired capacity of the group).

        Returns:
        The maximum size of the Auto Scaling group.

      • desiredCapacity

        public final Integer desiredCapacity()

        The desired capacity is the initial capacity of the Auto Scaling group after this operation completes and the capacity it attempts to maintain. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group.

        Returns:
        The desired capacity is the initial capacity of the Auto Scaling group after this operation completes and the capacity it attempts to maintain. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group.
      • defaultCooldown

        public final Integer defaultCooldown()

        Only needed if you use simple scaling policies.

        The amount of time, in seconds, between one scaling activity ending and another one starting due to simple scaling policies. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

      • hasAvailabilityZones

        public final boolean hasAvailabilityZones()
        For responses, this returns true if the service returned a value for the AvailabilityZones property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • availabilityZones

        public final List<String> availabilityZones()

        One or more Availability Zones for the group.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAvailabilityZones() method.

        Returns:
        One or more Availability Zones for the group.
      • healthCheckType

        public final String healthCheckType()

        A comma-separated value string of one or more health check types.

        The valid values are EC2, ELB, and VPC_LATTICE. EC2 is the default health check and cannot be disabled. For more information, see Health checks for Auto Scaling instances in the Amazon EC2 Auto Scaling User Guide.

        Only specify EC2 if you must clear a value that was previously set.

        Returns:
        A comma-separated value string of one or more health check types.

        The valid values are EC2, ELB, and VPC_LATTICE. EC2 is the default health check and cannot be disabled. For more information, see Health checks for Auto Scaling instances in the Amazon EC2 Auto Scaling User Guide.

        Only specify EC2 if you must clear a value that was previously set.

      • healthCheckGracePeriod

        public final Integer healthCheckGracePeriod()

        The amount of time, in seconds, that Amazon EC2 Auto Scaling waits before checking the health status of an EC2 instance that has come into service and marking it unhealthy due to a failed health check. This is useful if your instances do not immediately pass their health checks after they enter the InService state. For more information, see Set the health check grace period for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

        Returns:
        The amount of time, in seconds, that Amazon EC2 Auto Scaling waits before checking the health status of an EC2 instance that has come into service and marking it unhealthy due to a failed health check. This is useful if your instances do not immediately pass their health checks after they enter the InService state.

      • placementGroup

        public final String placementGroup()

        The name of an existing placement group into which to launch your instances. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances.

        A cluster placement group is a logical grouping of instances within a single Availability Zone. You cannot specify multiple Availability Zones and a cluster placement group.

        Returns:
        The name of an existing placement group into which to launch your instances. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances.

        A cluster placement group is a logical grouping of instances within a single Availability Zone. You cannot specify multiple Availability Zones and a cluster placement group.

      • vpcZoneIdentifier

        public final String vpcZoneIdentifier()

        A comma-separated list of subnet IDs for a virtual private cloud (VPC). If you specify VPCZoneIdentifier with AvailabilityZones, the subnets that you specify must reside in those Availability Zones.

        Returns:

      • hasTerminationPolicies

        public final boolean hasTerminationPolicies()
        For responses, this returns true if the service returned a value for the TerminationPolicies property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • terminationPolicies

        public final List<String> terminationPolicies()

        Valid values: units | vcpu | memory-mib

      • defaultInstanceWarmup

        public final 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.

        Returns:
        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.
