New services do not always deliver support for CloudFormation at the launch. If you work with CloudFormation, you can create a Custom Resource. With the new import functionality, once AWS adds native support for the resource, you can now import this resource into your template and remove the old custom resource.
This blog post describes the 4 stages:
Create the Custom Resource provider; a lambda function Deploy the resource using the previous Custom Resource provider Import the custom created resource into your stack Remove the custom resource from the stack, leaving the imported for future use In our example we assume SNS Topic is not yet supported by CloudFormation at launch.
