Azure Stack 上的 Azure 云和 IoT 中心上的 IoT 中心之间的差异Differences between IoT Hub on Azure Cloud and IoT Hub on Azure Stack
| 方面Aspect | 云上的 IoT 中心IoT Hub on Cloud | 堆栈上的 IoT 中心IoT Hub on Stack |
|---|---|---|
| 消息消耗Message Consumption | https://docs.microsoft.com/azure/iot-hub/iot-hub-devguide-messages-read-builtin | 默认情况下，消息将路由到与事件中心兼容的内置面向服务的终结点 (messages/events) 中。By default, messages are routed to the built-in service-facing endpoint (messages/events) that is compatible with Event Hubs. 在 Azure 云上，你可以通过提供 IoT 中心连接字符串或事件中心连接字符串从终结点访问消息。On Azure cloud, you can access the messages from the end point by providing either IoT Hub connection string or Event Hub connection string. 但是，在 Azure Stack 集线器上，只支持事件中心连接字符串。However, on Azure Stack hub, only event hub connection string is supported. |
后续步骤Next Steps
如果 IoT 中心在订阅中不可用，请与管理员联系，以 在 Azure Stack 中心资源提供程序上安装 Iot 中心。If IoT Hub isn't available in your subscription, work with your administrator to install the IoT Hub on Azure Stack Hub resource provider.
若要了解如何使用 IoT 中心，请参阅 Azure Iot 中心文档。To learn how to use IoT Hub, refer to the Azure IoT Hub documentation.
