<para>Heat is a service used to orchestrate multiple composite
|
|
cloud applications using the AWS CloudFormation template
|
|
format, through both an OpenStack-native ReST API and a
|
|
CloudFormation-compatible Query API.</para>
|
|
<para>The purpose of Heat is to provide a template based
|
|
orchestration for describing a cloud application by executing
|
|
appropriate OpenStack API calls to generate running cloud
|
|
applications, integrate other core components of OpenStack
|
|
into a one-file template system. The templates allow creation
|
|
of most OpenStack resource types such as instances, floating
|
|
ips, volumes, security groups, users, etc.</para>
