public Future<AttachInstancesResult> attachInstancesAsync(AttachInstancesRequest request)
AmazonAutoScalingAsync
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 Detach or attach instances in the Amazon EC2 Auto Scaling User Guide.

Completes the lifecycle action for the specified token or instance with the specified result.
This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:
(Optional) Create a launch template or launch configuration with a user data script that runs while an instance is in a wait state due to a lifecycle hook.
(Optional) Create a Lambda function and a rule that allows Amazon EventBridge to invoke your Lambda function when an instance is put into a wait state due to a lifecycle hook.
(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 wait state.
If you finish before the timeout period ends, send a callback by using the CompleteLifecycleAction API call.

To terminate all instances before deleting the Auto Scaling group, call the UpdateAutoScalingGroup API and set the minimum size and desired capacity of the Auto Scaling group to zero.

For more information, see Detach or attach instances in the Amazon EC2 Auto Scaling User Guide.

Creates or updates a lifecycle hook for the specified Auto Scaling group.
Lifecycle hooks let you create solutions that are aware of events in the Auto Scaling instance lifecycle, and then perform a custom action on instances when the corresponding lifecycle event occurs.
This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:
(Optional) Create a launch template or launch configuration with a user data script that runs while an instance is in a wait state due to a lifecycle hook.
(Optional) Create a Lambda function and a rule that allows Amazon EventBridge to invoke your Lambda function when an instance is put into a wait state due to a lifecycle hook.
(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 wait state using the RecordLifecycleActionHeartbeat API call.
If you finish before the timeout period ends, send a callback by using the CompleteLifecycleAction API call.

AmazonAutoScalingAsync
Starts an instance refresh.
This operation is part of the instance refresh feature in Amazon EC2 Auto Scaling, which helps you update instances in your Auto Scaling group. This feature is helpful, for example, when you have a new AMI or a new user data script. You just need to create a new launch template that specifies the new AMI or user data script. Then start an instance refresh to immediately begin the process of updating instances in the group.
If successful, the request's response contains a unique ID that you can use to track the progress of the instance refresh. To query its status, call the DescribeInstanceRefreshes API. To describe the instance refreshes that have already run, call the DescribeInstanceRefreshes API. To cancel an instance refresh that is in progress, use the CancelInstanceRefresh API.
An instance refresh might fail for several reasons, such as EC2 launch failures, misconfigured health checks, or
not ignoring or allowing the termination of instances that are in Standby
state or protected from
scale in. You can monitor for failed EC2 launches using the scaling activities. To find the scaling activities,
call the DescribeScalingActivities API.
If you enable auto rollback, your Auto Scaling group will be rolled back automatically when the instance refresh
fails. You can enable this feature before starting an instance refresh by specifying the
AutoRollback
property in the instance refresh preferences. Otherwise, to roll back an instance
refresh before it finishes, use the RollbackInstanceRefresh API.

implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.public Future<SuspendProcessesResult> suspendProcessesAsync(SuspendProcessesRequest request)
AmazonAutoScalingAsync
Suspends the specified auto scaling processes, or all processes, for the specified Auto Scaling group.
If you suspend either the Launch
or Terminate
process types, it can prevent other
process types from functioning properly. For more information, see Suspend and resume
Amazon EC2 Auto Scaling processes in the Amazon EC2 Auto Scaling User Guide.
To resume processes that have been suspended, call the ResumeProcesses API.

AmazonAutoScalingAsync
Terminates the specified instance and optionally adjusts the desired group size. This operation cannot be called on instances in a warm pool.
This call simply makes a termination request. The instance is not terminated immediately. When an instance is
terminated, the instance status changes to terminated
. You can't connect to or start an instance
after you've terminated it.
If you do not specify the option to decrement the desired capacity, Amazon EC2 Auto Scaling launches instances to replace the ones that are terminated.
By default, Amazon EC2 Auto Scaling balances instances across all Availability Zones. If you decrement the desired capacity, your Auto Scaling group can become unbalanced between Availability Zones. Amazon EC2 Auto Scaling tries to rebalance the group, and rebalancing might terminate instances in other zones. For more information, see Manual scaling in the Amazon EC2 Auto Scaling User Guide.

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.
