Google Cloud IoT Core is a fully managed service to easily and securely connect, manage, and ingest data from globally dispersed devices.

Google Cloud IoT Core is a fully managed service to easily and securely connect, manage, and ingest data from globally dispersed devices.

  • Connect all devices and gateways to Google Cloud Platform over standard protocols, such as MQTT, HTTP, through the protocol endpoints and manage all your devices as a single global system.
  • Enable end-to-end security using asymmetric key authentication over TLS 1.2; CA signed certificates can be used to verify device ownership.
  • Use REST APIs to automatically manage the registration, deployment, and operation of devices at scale. Also, use the APIs to retrieve and update device properties and state even when the devices are not connected.
