Cloud interoperability based on a generic cloud service description: Mapping OWL-S to GCSD

Abstract

The lack of standardized service descriptions in cloud environments causes the vendor lock-in, which hinders cloud service interoperability. Approaches like standards, brokers, and semantic technologies were proposed in the literature to enable cloud service interoperability. However, these propositions are specific to a certain technology or a particular cloud model, or they consider a specific cloud actor, which makes them restricted and not generic. In this paper, we discuss the importance of Cloud Service Description (CSD) standardization to enable cloud service interoperability. We propose a novel service interoperability model based on a generic CSD model (GCSD). The proposed transformation mediator uses mapping rules to transform heterogeneous cloud service descriptions into the GCSD uniform description. Consequently, it makes them interoperable. This work is in its early stages. Therefore, it covers only the transformation from OWL-S to the GCSD. Eventually, we provide use cases to illustrate the transformations from OWL-S to the GCSD.
