The OCCIware project aims at building a comprehensive engineering toolchain for managing Everything as a Service (XaaS). The objective is to dramatically decrease the cost of using or providing XaaS by breaking silos between layers and domains of Cloud Computing. Leveraging the Open Cloud Computing Interface (OCCI) standard-to-be, we are developing a model-driven engineering studio as well as generic runtimes adapted to various domains: Linked Open Data, cloud computing, platform as a service, Big Data, connected objects, etc. The project, funded by French Ministry of Industry, involves 10 academic and industrial partners and is supervised by a committee of 11 top scientists and industry experts.
