Open Stack

Hi Sergey,
I agree with your feeling, this is from the Heat Wiki page.
"Heat also endeavours to provide compatibility with the AWS CloudFormation template format, so that many existing CloudFormation templates can be launched on OpenStack."

Note also, there was another review that attempted implement this, but stalled.

Subject: [openstack-dev] [Heat] Status of the Support Conditionals in Heat templates

Hi Heaters,

On the last IRC meeting we had a question about Support Conditionals spec [1].
Previous attempt for this staff is here [2].
The example of first POC in Heat can be reviewed here [3]

As I understand we have not had any complete decision about this work.
So I'd like to clarify feelings of community about it. This clarification may be done as answers for two simple questions:
 - Why do we want to implement it?
 - Why do NOT we want to implement it?

My personal feeling is:
- Why do we want to implement it?
    * A lot of users wants to have similar staff.
    * It's already presented in AWS, so will be good to have this feature in Heat too.
 - Why do NOT we want to implement it?
    * it can be solved with Jinja [4] . However I don't think, that it's really important reason for blocking this work.

Please share your idea about two questions above.
It should allows us to eventually decide, want we implement it or not.
