In this illustration, six methods of connecting devices to Oracle IoT Cloud service are displayed.

  1. Industrial gateways:sensor and machines that uses proprietary protocols, and MODBUS connect to a gateway with Oracle IoT gateway Software installed to it that then connects to Oracle IoT Cloud Service by using the HTTP protocol.
  2. Directly Connected Devices: An On-board connector device connects to Oracle IoT Cloud service using the MQTT protocol.
  3. 3rd Party Device Clouds: Devices connect to 3rd Party device clouds using a propriety protocol and then the 3rd party device cloud connects to Oracle IoT Cloud Service using the HTTP protocol.
  4. Historian: Machines: Machines use SCADA to save their data in on-premise Historian systems which in turn pass on the data to Oracle IoT Cloud Service using HTTP protocol.
  5. Industrial Software Gateways: Machines use OPC-UA to communicate with On-premise software gateways on OPC-UA servers that in turn connect with Oracle IoT Cloud service using HTTP protocol.
  6. Network Service Providers: Providers of IoT network such as MVNO, LoRA, NB-IoT transmit device data collected from Telematics gateways or other sensors and then connect with Oracle IoT Cloud Service using HTTP protocol.
