Launch and manage stacks

OpenStack Orchestration is a service that you can use to orchestrate multiple composite cloud applications. This service supports the use of both the Amazon Web Services (AWS) CloudFormation template format through both a Query API that is compatible with CloudFormation and the native OpenStack Heat Orchestration Template (HOT) format through a REST API.

These flexible template languages enable application developers to describe and automate the deployment of infrastructure, services, and applications. The templates enable creation of most OpenStack resource types, such as instances, floating IP addresses, volumes, security groups, and users. Once created, the resources are referred to as stacks.

The template languages are described in the Template Guide <http://docs.openstack.org/developer/heat/template_guide/index. html> in the Heat developer documentation <http://docs. openstack.org/developer/heat/>.
