The Azure IoT Suite provides heterogeneous device support via the Azure IoT SDKs. The goal of the architecture is to enable secure, efficient, and robust communication between nearly any kind of device through a cloud/field gateway. The function of cloud/field gateway includes protocol adaptation which is required to connect existing and legacy devices to send telemetry to the cloud, and receive notifications in command & control scenario. A field gateway is a specialized device-appliance or general-purpose software that acts as a communication enabler and potentially, as a local device control system and device data processing hub. The key takeaway of session is to show you that it is easy and simple to implement practical cloud-assisted or cloud-based commercial IoT solutions. Come join this session as Fai demonstrates an Azure IoT protocol gateway which enables communication with Azure IoT Hub. It is a pass-through component that bridges traffic between connected IoT devices (e.g., over the MQTT protocol) and IoT Hub. In the demo, the protocol gateway is deployed on a hardware device meant for on-premises environments.
В докладе будет рассмотрен вопрос асинхронного ввода-вывода, который является одним первоочередных для масштабируемости приложений. Кроме того, будет подробно разобраны виды асинхронности; отличие CPU-bound и I/O-bound задач; подробно разобран разбор механизма "I/O Thread" в .NET на платформе Windows, а также особенности ASP.NET и ASP.NET Web API.
