Towards a Multi-tenancy Aware Cloud Service Composition

Cloud computing has gained a momentum by combining multi-tenant and scalable services in order to obtain a composed service and some added value. Therefore, it is important for composed cloud services to support multi-tenancy during the services matching. For this purpose, we tackle the problem of integrating multi-tenancy in cloud services composition and we determine crucial issues that can be solved. To do this, we propose a multi-tenant aware services composition approach to facilitate the dynamic services matching at run-time. This research is based on service patterns which are used within the composition process for integrating multi-tenancy architecture and reducing the difficulty of cloud services matching. Furthermore, we propose a middleware layer (Composition as a Service) for implementing our approach into conventional cloud architecture. The performed evaluation proves the efficiency of our approach for services based applications in the cloud computing.
