# Using CloudFormation to deploy Accelerate configuration changes
<a name="acc-mem-deploy-change-cfn"></a>

If you wish to deploy your `CustomerManagedAlarms` configuration profile using CloudFormation, you can use the following CloudFormation templates. Put your desired JSON configuration in the `AMSAlarmManagerConfigurationVersion.Content` field.

When you deploy the templates in a CloudFormation Stack or Stack Set, the deployment of the `AMSResourceTaggerDeployment` resource will fail if you have not followed the required JSON format for the configuration. See [Accelerate Configuration profile: monitoring](acc-mem-config-doc-format.md) for details on the expected format.

For help on deploying these templates as a CloudFormation stack or stack set, see the relevant AWS CloudFormation documentation below:
+ [Creating a stack on the AWS CloudFormation console](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-create-stack.html)
+ [Creating a stack with AWS CLI](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-cli-creating-stack.html)
+ [Creating a stack set](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-getting-started-create.html)

**Note**  
If you deploy a configuration version using one of these templates, and then subsequently delete the CloudFormation stack/stack set, the template configuration version will remain as the current deployed version, and no additional deployment will be made. If you wish to revert back to a default configuration, you will need to either manually deploy an empty configuration (i.e. just {}), or update your stack to an empty configuration, rather than deleting the stack.
