IoT gateways may be the unsung heroes of the Internet of Things world. Without them, there would likely be no expectations of tens of billions of IoT devices coming online in the next few years. In many respects, gateways are the glue that holds many IoT implementations together. They enable real-time analysis of IoT data and link multitudinous connected sensors and devices to the cloud. In addition, gateways act as a bridge between various sensor types and connectivity protocols, while helping to link equipment from an organization’s information technology (IT) and operation technology (OT) departments.
But gateways can also be single points of failure in IoT networks. In a poorly designed system, when a gateway goes down, critical functions stop. Preventing that outcome is possible, however, with an IoT gateway architecture based on the idea of clustering.
