OCCIware Outputs• A formal, model-driven platform to manage any Cloud resource
- Formal model of OCCI, on MIT's Alloy – Inria & TSP- OCCIware Studio, on Eclipse EMF & Sirius – Obeo- OCCIware@Runtime & console, using Models@Runtime – ActiveEon & Scalair- Deploy@OCCIware - ActiveEon & UJF
• 4 Use cases- Data Center as a Service / IaaS, on Scalair infrastructure- Big Data / HPC, on ActiveEon ProActive HPC platform- Linked Open Data, on Ozwillo app store's Datacore – Pôle Numérique & Open Wide- Deployment interoperability, on Linagora & ActiveEon's
• Open Source (OW2, Eclipse) and standardization (OGF) with help from a 10-strong international Scientific Orientation Committee
