Multi-tenancy Aware Configurable Service Discovery Approach in Cloud Computing

The multi-tenancy aware discovery of configurable Cloud services is one of the most important and difficult issues, because of multiplicity and non-standardization of their description in the Cloud. In this paper, relying on a feature model based specification of configurable WSDL services, we develop a multi-tenancy aware approach for their discovery. Our approach empowers multiple tenants to discover their desired service configured variants, considering individual variations. To do so, we reduce the problem of configurable matching to a tree matching problem and we adapt existing algorithms for this aim. The experimental results show the feasibility of our approach.
