Geoff, I am commenting primarily on your suggested use of jBPM as the orchestration engine, and less on the use of BPMN.
jBPM's is more suited for on premise or private cloud deployments. In a public cloud scenario, it will be challenging to use jBPM as a generic orchestration engine - jBPM requires the code for the orchestration tasks to be uploaded to the jBPM engine, or exposed as a public facing endpoint. The need to upload code to a shared orchestration engine on the cloud introduces challenges (security, isolation, scalability). The following blog post speaks to it in more detail- http://roshanagrawal777.blogspot.com/ From: Geoff O'Callaghan <[email protected]> Date: Tuesday, December 25, 2012 11:49 PM To: "[email protected]" <[email protected]> Subject: [Openstack] openstack orchestration Hi All, I'm interested in seeing where we can use BPMN based orchestration in openstack. Rather than putting all the context in here and having you scroll through it all, i've written a blogpost at http://ovirt.blogspot.com.au/2012/12/openstack-orchestration.html I'm very interested in your thoughts on this subject. Tks Geoff
