public void setMaxHealthyPercentage(Integer maxHealthyPercentage) {
        this.maxHealthyPercentage = maxHealthyPercentage;
    }
<p>
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.
</p>
<p>
If you specify <code>MaxHealthyPercentage</code>, you must also specify <code>MinHealthyPercentage</code>, 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.
</p>
<p>
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.
