The Cloud-computing paradigm advocates the use of re-sources available \"In the clouds\". In front of the multiplicity of cloud providers, it becomes cumbersome to manually tackle this heterogeneity. In this paper, the authors propose to de ne an abstraction layer used to model resources available in the clouds. This cloud modelling language (CloudML) allows cloud users to focus on their needs, i.e., the modelling the resources they expect to retrieve in the clouds. An automated provisioning engine is then used to automatically analyze these requirements and actually provision resources in clouds.
