Constructor Details

#initialize(max_capacity:, min_capacity:) ⇒ ScalingConstraintsProperty

Returns a new instance of ScalingConstraintsProperty.

Parameters:

  • max_capacity (Numeric) —

    The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow.

  • min_capacity (Numeric) —

    The lower boundary of EC2 instances in an instance group below which scaling activities are not allowed to shrink.

Instance Attribute Details

#max_capacity ⇒ Numeric (readonly)

The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow.

Scale-out activities will not add instances beyond this boundary.

Returns:

end

#min_capacity ⇒ Numeric (readonly)

The lower boundary of EC2 instances in an instance group below which scaling activities are not allowed to shrink.

Scale-in activities will not terminate instances below this boundary.

Returns:

  • (Numeric)
