Hybrid Approach for Cloud Service Discovery System

Cloud computing delivers services over the internet based on pay as you use financial model. Cloud providers publish service advertisements in different format (text, files, table and images) on the Internet. On the other hand, cloud consumers spend a lot of time and effort to find the appropriate cloud service using public search engines. Nowadays, cloud service discovery process considers as an important challenge for cloud service consumers, especially with massive increase in the number of available cloud services. In this paper, we present a layered architecture for cloud service discovery system. Additionally, we present a hybrid approach for cloud service discovery based on semantic and numerical similarity. Furthermore, we present domain ontology to create a shared understanding for cloud service domain. Finally, we implement proposed approach with protégé and SPARQL. Empirical results show the correctness and completeness of proposed system.
