[openstack-dev] [Heat] Heat Resource Plugin for third party storage

Hello,


We come across this:
http://docs.openstack.org/developer/heat/pluginguide.html


Looks like it solves three of the purposes listed below:

1. Define a custom resource type with properties and attributes
2. Register the resource to the Hear orchestrator
3. Write a driver/plugin (most likely the Life Cycle methods) which can
create/manage the resources when encounter from the Heat orchestration
engine.


Am I right?


Now the question is: in one place it is mentioned as:

"
It defines methods corresponding to the life cycle as well as the basic
hooks for plug-ins to handle the work of communicating with specific
down-stream services
"


Can this down-stream service be *anything* (say a third-party storage
array)? Or it has to be a OpenStack service only?




Thanks in advance,
Pradip
