“…The proposed methodology and the proposed RBPF system, augmented with semantics and clustering support, are presented in "Reconfigurable BPaaS-Based SaaS Services Federation System" section. "Experimentation and Discussion" section validates our proposal by comparing the effectiveness and efficiency of the proposed approach, comparing to the ones proposed in [26]. Finally, the conclusion and the ongoing work are described in "Conclusion and Future Work" section.…”

“…This is because the number of calculated services clusters is a constant. In our previous work [26], that complexity was O(n × m!) in the worst case, where n is the number of activities in the workflow and m the number of SaaS services.…”

“…A first evaluation of the RBPF system highlighted the need to improve the efficiency of the proposed composition algorithm [26]. We explore in this article clustering techniques to partition the service space into different classes in order to reduce the search space and improve the behavior of the composition algorithms in the presence of a high number of SaaS service in the RBPF system.…”

Business Process as a Service (BPaaS) met a considerable proliferation and an exponential emergence as a new Cloud service for delivering complex and complete business applications. To better position themselves in the harshly competitive Cloud services market, BPaaS providers should offer to their clients, flexible services responding both to their functional and non-functional requirements. This article proposes a Reconfigurable BPaaS-based SaaS services Federation system (RBPF) allowing flexible support of user requirements changes. RBPF proposes to end-users minimal on the fly compositions whenever a reconfiguration is required. To do so, Boolean Satisfiability Problem-based algorithms are adopted to select the minimal reconfiguration. To reduce composition candidates research space, we propose new algorithms to group BPaaS services that are likely to compose within the same cluster. The clustering process leverages semantic Linked Open Data similarity measures to match service capabilities and identify composable ones.
