  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ 'V1', 'V2' ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => 'Val1' },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to

DESCRIPTION

With Application Auto Scaling, you can automatically scale your AWS resources. The experience similar to that of Auto Scaling. You can use Application Auto Scaling to accomplish the following tasks:

• Define scaling policies to automatically scale your AWS resources

• Scale your resources in response to CloudWatch alarms

• View the history of your scaling events

Application Auto Scaling can scale the following AWS resources:

• Amazon ECS services. For more information, see Service Auto Scaling in the Amazon EC2 Container Service Developer Guide.

• Amazon EC2 Spot fleets. For more information, see Automatic Scaling for Spot Fleet in the Amazon EC2 User Guide.

• Amazon EMR clusters. For more information, see Using Automatic Scaling in Amazon EMR in the Amazon EMR Management Guide.

For a list of supported regions, see AWS Regions and Endpoints: Application Auto Scaling in the AWS General Reference.

METHODS

DeleteScalingPolicy(PolicyName => Str, ResourceId => Str, ScalableDimension => Str, ServiceNamespace => Str)

Each argument is described in detail in: Paws::ApplicationAutoScaling::DeleteScalingPolicy

Returns: a Paws::ApplicationAutoScaling::DeleteScalingPolicyResponse instance

  Deletes the specified Application Auto Scaling scaling policy.

Deleting a policy deletes the underlying alarm action, but does not delete the CloudWatch alarm associated with the scaling policy, even if it no longer has an associated action.

To create a scaling policy or update an existing one, see PutScalingPolicy.

DeregisterScalableTarget(ResourceId => Str, ScalableDimension => Str, ServiceNamespace => Str)

Each argument is described in detail in: Paws::ApplicationAutoScaling::DeregisterScalableTarget

Returns: a Paws::ApplicationAutoScaling::DeregisterScalableTargetResponse instance

  Deregisters a scalable target.

Deregistering a scalable target deletes the scaling policies that are associated with it.

To create a scalable target or update an existing one, see RegisterScalableTarget.

DescribeScalableTargets(ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, ResourceIds => ArrayRef[Str|Undef], ScalableDimension => Str])

Each argument is described in detail in: Paws::ApplicationAutoScaling::DescribeScalableTargets

Returns: a Paws::ApplicationAutoScaling::DescribeScalableTargetsResponse instance

  Provides descriptive information about the scalable targets in the
specified namespace.

You can filter the results using the ResourceIds and ScalableDimension parameters.

To create a scalable target or update an existing one, see RegisterScalableTarget. If you are no longer using a scalable target, you can deregister it using DeregisterScalableTarget.

DescribeScalingActivities(ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, ResourceId => Str, ScalableDimension => Str])

Each argument is described in detail in: Paws::ApplicationAutoScaling::DescribeScalingActivities

Returns: a Paws::ApplicationAutoScaling::DescribeScalingActivitiesResponse instance

  Provides descriptive information about the scaling activities in the
specified namespace from the previous six weeks.

You can filter the results using the ResourceId and ScalableDimension parameters.

Scaling activities are triggered by CloudWatch alarms that are associated with scaling policies. To view the scaling policies for a service namespace, see DescribeScalingPolicies. To create a scaling policy or update an existing one, see PutScalingPolicy.

DescribeScalingPolicies(ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, PolicyNames => ArrayRef[Str|Undef], ResourceId => Str, ScalableDimension => Str])

Each argument is described in detail in: Paws::ApplicationAutoScaling::DescribeScalingPolicies

Returns: a Paws::ApplicationAutoScaling::DescribeScalingPoliciesResponse instance

  Provides descriptive information about the scaling policies in the
specified namespace.

You can filter the results using the ResourceId, ScalableDimension, and PolicyNames parameters.

To create a scaling policy or update an existing one, see PutScalingPolicy. If you are no longer using a scaling policy, you can delete it using DeleteScalingPolicy.

PutScalingPolicy(PolicyName => Str, ResourceId => Str, ScalableDimension => Str, ServiceNamespace => Str, [PolicyType => Str, StepScalingPolicyConfiguration => Paws::ApplicationAutoScaling::StepScalingPolicyConfiguration])

Each argument is described in detail in: Paws::ApplicationAutoScaling::PutScalingPolicy

Returns: a Paws::ApplicationAutoScaling::PutScalingPolicyResponse instance

  Creates or updates a policy for an Application Auto Scaling scalable
target.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scaling policy applies to the scalable target identified by those three attributes. You cannot create a scaling policy without first registering a scalable target using RegisterScalableTarget.

To update a policy, specify its policy name and the parameters that you want to change. Any parameters that you don't specify are not changed by this update request.

You can view the scaling policies for a service namespace using DescribeScalingPolicies. If you are no longer using a scaling policy, you can delete it using DeleteScalingPolicy.

RegisterScalableTarget(ResourceId => Str, ScalableDimension => Str, ServiceNamespace => Str, [MaxCapacity => Int, MinCapacity => Int, RoleARN => Str])

Each argument is described in detail in: Paws::ApplicationAutoScaling::RegisterScalableTarget

Returns: a Paws::ApplicationAutoScaling::RegisterScalableTargetResponse instance

  Registers or updates a scalable target. A scalable target is a resource
that Application Auto Scaling can scale out or scale in. After you have
registered a scalable target, you can use this operation to update the
minimum and maximum values for your scalable dimension.

After you register a scalable target, you can create and apply scaling policies using PutScalingPolicy. You can view the scaling policies for a service namespace using DescribeScalableTargets. If you are no longer using a scalable target, you can deregister it using DeregisterScalableTarget.

PAGINATORS

Paginator methods are helpers that repetively call methods that return partial results

DescribeAllScalableTargets(sub { },ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, ResourceIds => ArrayRef[Str|Undef], ScalableDimension => Str])

DescribeAllScalableTargets(ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, ResourceIds => ArrayRef[Str|Undef], ScalableDimension => Str])

If passed a sub as first parameter, it will call the sub for each element found in :

 - ScalableTargets, passing the object as the first parameter, and the string 'ScalableTargets' as the second parameter 

If not, it will return a a Paws::ApplicationAutoScaling::DescribeScalableTargetsResponse instance with all the params; from all the responses. Please take into account that this mode can potentially consume vasts ammounts of memory.

DescribeAllScalingActivities(sub { },ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, ResourceId => Str, ScalableDimension => Str])

DescribeAllScalingActivities(ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, ResourceId => Str, ScalableDimension => Str])

If passed a sub as first parameter, it will call the sub for each element found in :

 - ScalingActivities, passing the object as the first parameter, and the string 'ScalingActivities' as the second parameter 

If not, it will return a a Paws::ApplicationAutoScaling::DescribeScalingActivitiesResponse instance with all the params; from all the responses. Please take into account that this mode can potentially consume vasts ammounts of memory.

DescribeAllScalingPolicies(sub { },ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, PolicyNames => ArrayRef[Str|Undef], ResourceId => Str, ScalableDimension => Str])

DescribeAllScalingPolicies(ServiceNamespace => Str, [MaxResults => Int, NextToken => Str, PolicyNames => ArrayRef[Str|Undef], ResourceId => Str, ScalableDimension => Str])

If passed a sub as first parameter, it will call the sub for each element found in :

 - ScalingPolicies, passing the object as the first parameter, and the string 'ScalingPolicies' as the second parameter 

If not, it will return a a Paws::ApplicationAutoScaling::DescribeScalingPoliciesResponse instance with all the params; from all the responses. Please take into account that this mode can potentially consume vasts ammounts of memory.
