Here is an interesting trend. Moxa released a series of IIoT gateways optimized for Microsoft Azure.
Moxa launched the AIG-300 Series of IIoT gateways. Optimized for seamless integration with the Microsoft Azure IoT Edge computing platform, AIG-300 gateways provide the stable connectivity needed in distributed and unmanned sites to collect, store, process, and analyze operational data from sensors and other IIoT devices.
As edge computing use cases continue to evolve, Moxa AIG-300 gateways enable flexible and secure cloud connectivity by leveraging: Arm CortexA7 dual-core 1 GHz processors, pre-loaded Azure IoT Edge and Moxa ThingsPro Edge software, and versatile I/O options for Ethernet, CAN, RS-232/422/485, USB, and four digital (DI/DO) interfaces. For system integrators with wireless communication needs, the AIG-300 comes with LTE cellular, GPS and Wi-Fi antenna connectors.
