You could use the heat project to provide autoscaling.
The way this would work is you:
1 create an CloudFormations style template with your application (OpenShift/CloudFoundry)
2 you setup an autoscale group and alarm resource in the template
3 you post the metric of interest in your application to our Cloudwatch
   (see the calls to cfn-push-stats)
     
as an example look at:
https://github.com/heat-api/heat/blob/master/templates/AutoScalingMultiAZSample.template

What happens is you setup a threshold that triggers a scale up and scale down action.
