Is there any template/tool/architecture supported by openstack in order to auto-scale elastically VMs depending upon the CPU utilization?

Elastically allocate resources like CPU required, Memory etc to instances during run-time or like HOT which supports only add/ remove VM based on the metadata...BUT IS THERE POSSIBILITY TO SCALE RESOURCES OF THE EXISTING INSTANCES?

Thank you for your response. I looked into Heat template, according to my understanding from it HEAT auto-scales by Adding/Deleting VMs But I am looking to alter existing VM/instance's resources

Those specs are deprecated.We now have the senlin service released with Mitaka. It is a clustering service (http://wiki.openstack.org/wiki/senlin). Requirements like this one can be easily met using senlin now. Before deleting nodes from a cluster, you have a choice to do an election.
