1. The OGFOpen Cloud Computing Interface Shlomo Swidler OGF OCCI WG Member 3December 2009

2. Agenda Goal of OCCI Who is OCCI Current status A quick look

3. OCCI Vision:Open Cloud Ecosystem Open Formats Open Cloud Open Interfaces Open Data Open Source

4. OCCI Vision:Open Cloud Ecosystem Open Formats Copyrights – free to use Trademarks – compliance enforcement only Patents – royalty-free, forever Open Cloud Open Interfaces Open Data Implementations – multiple, complete, interoperable, open license Open Source

5. Goal of OCCI Interoperability Let different cloud systemswork together Portability Move services between clouds Integration Wire up cloud with legacy At all levels of the stack

6. Who is OCCI Open Grid Forum Working Group OGF IP umbrella for copyrights, patents, trademarks More than 200 participants Industry: Rackspace, GoGrid, Sun, RESERVOIR, … Academia: UCMadrid (OpenNebula), SLA@SOI w/Intel, … Service providers: CohesiveFT, RabbitMQ, … End users, developers

7. Current Status of OCCI Infrastructure layer spec finalized, submitted for review OpenNebula reference implementation underway Other implementations in the works, too… Working on Extensions (reservations, snapshots, etc.) Researching Platform layer Proposed Roadmap: Draft Platform spec - March 2010 Draft Application spec – October 2010 Final – early 2011

8. 20,000-foot Look at OCCI Protocol Lightweight, extensible Format-agnostic Built on HTTP, RESTful Create: HTTP POST Retrieve: HTTP GET Update: HTTP GET & HTTP PUT Delete: HTTP DELETE OCCI Application OCCI Platform OCCI Infrastructure HTTP Header Rendering XHTML5 + RDFa Rendering OCCI Core Extensions

9. 5,000-foot Look at OCCI GET http://abc.com/uid123foobar/ * Provider Instance * HTTP LINK header Compute * Storage * Links Network * Operations * Attributes OCCI Atom-like categories
