end

#default_instance_warmup ⇒ `Integer`

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.

#desired_capacity_type ⇒ `String`

For more information, see [Create a mixed instances 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`

#health_check_grace_period ⇒ `Integer`

#health_check_type ⇒ `String`

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

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

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

#max_size ⇒ `Integer`

The maximum size of the Auto Scaling group.

<note markdown=“1”> 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).

The name of an existing placement group into which to launch your instances. To remove the placement group setting, pass an empty string for ‘placement-group`. For more information about placement groups, see [Placement groups] in the *Amazon EC2 User Guide for Linux Instances*.

<note markdown=“1”> 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.
