This document describes an implementation of a SCADA system powered by MQTT & OPC-UA protocols and hosted within the Google Cloud Platform system. This combination allows to have integrated, scalable, secure and reliable industrial communications while allowing real-time data acquisition and sensor feed that can then be used in real-time OEE tracking or predictive maintenance models, to name some examples. This in line with the Industry 4.0 initiatives mainly fueled by data and machine learning autonomous systems.
