-- __We strongly recommend that all Auto Scaling groups use launch
-- templates to ensure full functionality for Amazon EC2 Auto Scaling and
-- Amazon EC2.__
--
-- Updates the configuration for the specified Auto Scaling group.
--
-- To update an Auto Scaling group, specify the name of the group and the
-- property that you want to change. Any properties that you don\'t specify
-- are not changed by this update request. The new settings take effect on
-- any scaling activities after this call returns.
--
-- If you associate a new launch configuration or template with an Auto
-- Scaling group, all new instances will get the updated configuration.
-- Existing instances continue to run with the configuration that they were
-- originally launched with. When you update a group to specify a mixed
-- instances policy instead of a launch configuration or template, existing
-- instances may be replaced to match the new purchasing options that you
-- specified in the policy. For example, if the group currently has 100%
-- On-Demand capacity and the policy specifies 50% Spot capacity, this
-- means that half of your instances will be gradually terminated and
-- relaunched as Spot Instances. When replacing instances, Amazon EC2 Auto
-- Scaling launches new instances before terminating the old ones, so that
-- updating your group does not compromise the performance or availability
-- of your application.
--
-- Note the following about changing @DesiredCapacity@, @MaxSize@, or
-- @MinSize@:
--
-- -   If a scale-in activity occurs as a result of a new @DesiredCapacity@
--     value that is lower than the current size of the group, the Auto
--     Scaling group uses its termination policy to determine which
--     instances to terminate.
--
-- -   If you specify a new value for @MinSize@ without specifying a value
--     for @DesiredCapacity@, and the new @MinSize@ is larger than the
--     current size of the group, this sets the group\'s @DesiredCapacity@
--     to the new @MinSize@ value.
--
-- -   If you specify a new value for @MaxSize@ without specifying a value
--     for @DesiredCapacity@, and the new @MaxSize@ is smaller than the
--     current size of the group, this sets the group\'s @DesiredCapacity@
--     to the new @MaxSize@ value.
--
-- To see which properties have been set, call the
-- DescribeAutoScalingGroups API. To view the scaling policies for an Auto
-- Scaling group, call the DescribePolicies API. If the group has scaling
-- policies, you can update them by calling the PutScalingPolicy API.
