Automated Deployment of HDP in AWS

HI,

I deploy everything in AWS. When designing automated deployment I typically use a combination of CloudFormation and SaltStack. To deploy HDP, however, I think I should do things a bit differently and leverage Ambari. I think I will deploy all of my EC2 instances with CloudFormation, use Saltstack to install and start Ambari on one EC2 instance then script the execution of Ambari Blueprints to deploy the Hadoop components on other EC2 instances. Does this sound like a reasonable approach or am I reinventing the wheel? Any suggestions to do this in a more streamlined fashion?

Thanks,
Scott Edwards
