This document discusses leveraging computational power at the edge of IoT/M2M solutions using Informix in an IoT gateway architecture. It begins with an overview of IoT solutions focusing on utilities and smart energy. It then describes a Java/OSGi-based OT architecture and building blocks for processing data and integrating with enterprise IT systems using Informix. Example use cases are provided and it concludes that such an architecture can reduce costs and complexity while preserving customer value propositions.
