Integrate JIRA Ondemand instance with on premises instance

Question

Our mother company has an on demand instance of JIRA where they record support issues coming in from internal and external customers. Our R&D division responds to development and 2, 3rd tier support issues. R&D would like to keep the autonomy of Ondemand while being able to respond to support tickets on the mother company. Here is what our requirements would look like:

* Ticket open in mother company project > creates a ticket in R&D
* Ticket type edited in R&D > changed in mother company
* Ticket comments in R&D > added to mother company
* Ticket comments in mother company > added to R&D
* Ticket status changed in R&D > changed in mother company
* Ticket status changed in mother company > changed in R&D

Thanks for this answer. It's a good starting point.

As Boris has mentioned such level of integration does not exist using native functionality, but with some custom development it could be done, see https://developer.atlassian.com/static/connect/docs/modules/jira/webhook.html as a starting point... 
Basically you will need couple of plugins to be developed, one for on-demand with webhooks and another for your on-premise JIRA with custom jira plugin to do the job.

Intersting task to solve :-)
but the main prerequisite is to have your R&D JIRA accessible from internet (or having another server to be visible on internet that can play the proxy role for your R&D JIRA)

This level of integration does not exist using JIRA's native functionality.

You can use Application Links and it's functionality between both the cloud and server instance as long as the server instance can be accessed via some public URL. If the server install has an SSL cert it must be signed by a major CA in order for the cloud server to accept it, self signed will not work.
