# Set up automatic scaling for your Amazon MSK cluster
<a name="msk-autoexpand-setup"></a>

You can use the Amazon MSK console, the Amazon MSK API, or CloudFormation to implement automatic scaling for storage. CloudFormation support is available through [Application Auto Scaling](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-applicationautoscaling-scalabletarget.html).

**Note**  
You can't implement automatic scaling when you create a cluster. You must first create the cluster, and then create and enable an auto-scaling policy for it. However, you can create the policy while Amazon MSK service creates your cluster.

# Set up automatic scaling using the Amazon MSK AWS Management Console
<a name="msk-autoexpand-setup-console"></a>

This process describes how to use the Amazon MSK console to implement automatic scaling for storage.

1. Sign in to the AWS Management Console, and open the Amazon MSK console at [https://console.aws.amazon.com/msk/home?region=us-east-1\$1/home/](https://console.aws.amazon.com/msk/home?region=us-east-1#/home/).

1. In the list of clusters, choose your cluster. This takes you to a page that lists details about the cluster.

1. In the **Auto scaling for storage** section, choose **Configure**.

1. Create and name an auto-scaling policy. Specify the storage utilization target, the maximum storage capacity, and the target metric.

1. Choose `Save changes`.

When you save and enable the new policy, the policy becomes active for the cluster. Amazon MSK then expands the cluster's storage when the storage utilization target is reached.

# Set up automatic scaling using the CLI
<a name="msk-autoexpand-setup-cli"></a>

This process describes how to use the Amazon MSK CLI to implement automatic scaling for storage.

1. Use the [ RegisterScalableTarget](https://docs.aws.amazon.com/cli/latest/reference/application-autoscaling/#available-commands) command to register a storage utilization target.

1. Use the [ PutScalingPolicy](https://docs.aws.amazon.com/cli/latest/reference/application-autoscaling/#available-commands) command to create an auto-expansion policy.

# Set up automatic-scaling for Amazon MSK using the API
<a name="msk-autoexpand-setup-api"></a>

This process describes how to use the Amazon MSK API to implement automatic scaling for storage.

1. Use the [ RegisterScalableTarget](https://docs.aws.amazon.com/autoscaling/application/APIReference/API_RegisterScalableTarget.html) API to register a storage utilization target.

1. Use the [ PutScalingPolicy](https://docs.aws.amazon.com/autoscaling/application/APIReference/API_PutScalingPolicy.html) API to create an auto-expansion policy.
