The minimum number of instances allowed in the Amazon EC2 Auto Scaling group. During automatic scaling events,
Amazon GameLift FleetIQ and Amazon EC2 do not scale down the group below this minimum. In production, this value
should be set to at least 1. After the Auto Scaling group is created, update this value directly in the Auto
Scaling group using the Amazon Web Services console or APIs.
