The Distributed Management Task Force (DMTF) Cloud Infrastructure Management Interface (CIMI) Model and REST Interface over HTTP cloud spec draft is now out for public comment. CIMI was formed from input by more than 20 organizations and will continue to develop based on feedback. Reference implementations should be out soon. Download the draft here.
A whitepaper for background on CIMI use is also available, as is a mapping spec relative to the Common Information Model (CIM).
