A journal paper of UBITECH, in collaboration with the Aristotle University of Thessaloniki, the International Hellenic University and the Centre of Research & Technology Hellas, has been accepted for publication at the Elsevier Journal of Expert Systems with Applications (Impact Factor: 2,981). In this paper, Panagiotis Gouvas and his co-authors present a the recommendation algorithm that has been developed on top of a unified PaaS semantic model, for providing the application developer with recommendations about the best-matching Cloud PaaS offering. The algorithm consists of: a) a matchmaking part, where the functional parameters of the application are taken into account to rule out inconsistent offerings, and b) a ranking part, where the non-functional parameters of the application are considered to score and rank offerings. ?he algorithm is extensively evaluated showing linear scalability to the number of offerings and application requirements. Furthermore, it is extensible upon future semantic model extensions, because it is agnostic to domain specific concepts and parameters, using SPARQL template queries.
