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
|
|
:term:`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/>`_.
