HEAT Orchestration [[https://www.openstack.org/software/releases/zed/components/heat| HEAT Orchestration]] Heat orchestrates the infrastructure resources for a cloud application based on templates in the form of text files that can be treated like code. Heat provides both an OpenStack-native ReST API and a CloudFormation-compatible Query API. Heat also provides an autoscaling service that integrates with the OpenStack Telemetry services, so you can include a scaling group as a resource in a template.
