Dear OCCI-Workgroup,

i have a question concerning the OCCI Compute instance actions.

Comparing to the Amazon EC2-API, OCCI obviously delivers no action to terminate an Instance. Terminating in the Amazon-API means, that the instance is shut down and won´t be visible after one hour. The Action you listed in the GFD-P-R.184 on page 5 gives only the possibility to hibernate or suspend.

Is that the same or am I just confused :) ?

Thanks for clearing that up for me !!!

Feel free to answer in German :)

Keep up the good work,

Kind regards, Kim Rohner _______________________________________________ occi-wg mailing list occi-wg@ogf.org http://www.ogf.org/mailman/listinfo/occi-wg

A method - the transition from inactive to terminal state would be 'terminate'. The action of 'stop' and http-delete is certainly the only way to do it currently but as Kim's question shows, this is perhaps not particularly intuitive.

Yes, agreed on the non-intuitive part :) Is it provider specific what happens if you http-delete a running Compute instance? It could be equivalent to the stop-terminate case... Using Actions to Create/Delete Resource instances seems to push to usage of actions a bit to far IMO. /Ralf On Mon, 12 Sep 2011 14:13:51 +0000, "Edmonds, AndrewX" wrote: there

Agreed. Perhaps as a note I can append "termination of a resource instance is performed using HTTP DELETE (see section x.y.z)"?
