Recent research works when benchmarking Data Stream Processing and IoT platforms, report latencies on the order of tens of seconds and thus they are not suited for time-critical applications. Such platforms mainly use loosely coupled components with asynchronous communication. In this work, we present an alternative novel approach. We propose a novel End-to-End Synchronous, Distributed Architecture for Large-Scale, High-Bandwidth, Ultra-Low Latency Data Stream Processing which achieves latencies on the order of milliseconds. Through our Big Data Stream analysis experiments performed over the ARIS High Performance Computing facility of the National Infrastructures for Research and Technology S.A. (GRNET S.A.) - an EGI Council Participant, we have demonstrated the suitability of our architecture for time-sensitive applications.
