FERARI: a prototype for complex event processing over streaming multi-cloud platformsFERARI: a prototype for complex event processing over streaming multi-cloud platforms Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2018-10-112016enIn this demo, we present FERARI, a prototype that enables realtime Complex Event Processing (CEP) for large volume event data streams over distributed topologies. Our prototype constitutes, to our knowledge, the first complete, multi-cloud based end-to-end CEP solution incorporating: a) a user-friendly, web-based query authoring tool, (b) a powerful CEP engine implemented on top of a streaming cloud platform, (c) a CEP optimizer that chooses the best query execution plan with respect to low latency and/or reduced inter-cloud communication burden, and (d) a query analytics dashboard encompassing graph and map visualization tools to provide a holistic picture with respect to the detected complex events to final stakeholders. As a proof-of-concept, we apply FERARI to enable mobile fraud detection over real, properly anonymized, telecommunication data from T-Hrvatski Telekom network in Croatia.http://creativecommons.org/licenses/by/4.0/2093-2096ACM SIGMOD International Conference on Management of DataProceedings of the ACM SIGMOD International Conference on Management of Data Flouris Ioannis Φλουρης Ιωαννης Manikaki Vasiliki Μανικακη Βασιλικη Giatrakos Nikolaos Γιατρακος Νικολαος Deligiannakis Antonios Δεληγιαννακης Αντωνιος Garofalakis Minos Γαροφαλακης Μινως Mock Michael Bothe Sebastian Skarbovsky Inna Fournier Fabiana Štajcer Marko Križan Tomislav Yom-Tov, Jonathan Čurin Taji Association for Computing Machinery Information systems Networks Computer systems organization
