IoT Platform connects devices to the cloud and forwards device data to other Alibaba Cloud products for storage and processing, providing the foundation for IoT applications.
Devices
Use the protocols and SDKs integrated with IoT Platform to manage devices in the cloud.
IP devices: These devices, such as Wi-Fi devices, support the TCP/IP protocol stack. You can directly integrate Link SDK with them.
Non-IP devices: These devices, such as ZigBee, BT, KNX, and ModBus devices, do not support the TCP/IP protocol stack. They must connect to Alibaba Cloud IoT Platform through a gateway device that has Link SDK integrated. Sub-devices establish a connection through this gateway proxy. The communication method between the sub-device and the gateway is user-defined. For more information about connecting sub-devices using C Link SDK, see Overview.
-
Cloud gateway devices: IoT Platform supports direct device connections through a cloud gateway using open source protocols such as MQTT, JT/T 808, or GB/T 32960.
-
IoT as Bridge devices: IoT Platform supports MQTT, CoAP, and HTTPS but not protocols such as GB/T 26875.3-2011 or Modbus. For unsupported protocols, use the IoT as Bridge SDK to build a bridge service that creates a bidirectional data tunnel between the device or platform and Alibaba Cloud IoT Platform.
Alibaba Cloud IoT Platform
After a device connects to IoT Platform, it reports data to the cloud. IoT Platform collects, forwards, stores, and analyzes device data with real-time monitoring. The platform also provides security authentication and access policies to protect data on devices and in the cloud.
Available capabilities are listed in Features and Other Alibaba Cloud IoT services.
Integrate other Alibaba Cloud products with IoT Platform to enable message communication, data forwarding, and storage between devices and servers. Message communication.
