ASG Capacity Attributes
These three settings define the boundaries within which the Auto Scaling Group operates. They ensure that your application has enough resources without exceeding your budget.
Minimum Capacity: The floor value; ASG will never terminate instances below this number even if load is zero.
Maximum Capacity: The ceiling value; ASG will never scale out beyond this number, protecting you from runaway costs.
Desired Capacity: The number of instances the ASG attempts to maintain at any given time. Scaling policies update this value.
