Abstract
As Clouds mature and become ubiquitous, marketplace environments are developed facilitating the provision of services in a manner that emphasizes on the modular composition of individual services across different providers that crosscut the cloud service stack layers (i.e. composition of XaaS) to fulfil customers' requirements. Besides acting as intermediaries for the search, selection and trading of services, such marketplaces should also support the complete service lifecycle and the consolidation of offerings from different providers with varying and often contradicting business goals. In this paper we present a one-stop cloud marketplace solution that addresses the aforementioned challenges while enabling the simulation of different business cases to optimize service offerings according to a wide and dynamic set of parameters. Moreover, the proposed solution introduces advanced aggregated price models and integrates a new resolution approach that incorporates business intelligence into the search and selection processes. We also demonstrate the operation of the implemented approach and evaluate its effectiveness using a real-world scenario, based on a taxi fleet management application.
