#include Amazon EC2 Auto Scaling is
* designed to automatically launch or terminate EC2 instances based on
* user-defined scaling policies, scheduled actions, and health checks. Use this
* service with AWS Auto Scaling, Amazon CloudWatch, and Elastic Load
* Balancing. For more information, including information about granting IAM
* users required permissions for Amazon EC2 Auto Scaling actions, see the Amazon
* EC2 Auto Scaling User Guide. Attaches one or more EC2 instances to the specified Auto Scaling group. When you attach instances, Amazon EC2 Auto Scaling increases the desired
* capacity of the group by the number of instances being attached. If the number
* of instances being attached plus the desired capacity of the group exceeds the
* maximum size of the group, the operation fails. If there is a Classic
* Load Balancer attached to your Auto Scaling group, the instances are also
* registered with the load balancer. If there are target groups attached to your
* Auto Scaling group, the instances are also registered with the target
* groups. For more information, see Attach

Creates or updates a lifecycle hook for the specified Auto Scaling group.
*A lifecycle hook tells Amazon EC2 Auto Scaling to perform an action on an * instance when the instance launches (before it is put into service) or as the * instance terminates (before it is fully terminated).
This step is a part * of the procedure for adding a lifecycle hook to an Auto Scaling group:
(Optional) Create a Lambda function and a rule that allows CloudWatch * Events to invoke your Lambda function when Amazon EC2 Auto Scaling launches or * terminates instances.
(Optional) Create a notification target * and an IAM role. The target can be either an Amazon SQS queue or an Amazon SNS * topic. The role allows Amazon EC2 Auto Scaling to publish lifecycle * notifications to the target.
Create the lifecycle hook. * Specify whether the hook is used when the instances launch or terminate. *
If you need more time, record the lifecycle action heartbeat * to keep the instance in a pending state using the * RecordLifecycleActionHeartbeat API call.
If you finish * before the timeout period ends, complete the lifecycle action using the * CompleteLifecycleAction API call.
For more * information, see Amazon * EC2 Auto Scaling Lifecycle Hooks in the Amazon EC2 Auto Scaling User * Guide.
If you exceed your maximum limit of lifecycle hooks, which by * default is 50 per Auto Scaling group, the call fails.
You can view the * lifecycle hooks for an Auto Scaling group using the * DescribeLifecycleHooks API call. If you are no longer using a lifecycle * hook, you can delete it by calling the DeleteLifecycleHook * API.

Terminates the specified instance and optionally adjusts the desired group * size.

Updates the configuration for the specified Auto Scaling group.
To * update an Auto Scaling group, specify the name of the group and the parameter * that you want to change. Any parameters 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.
