Azure IoT Development Cookbook: Develop and manage robust IoT solutions
Microsoft’s end-to-end IoT platform is a comprehensive IoT offering, allowing enterprises to build and realize value from IoT solutions efficiently. It is essential to develop robust and reliable solutions for your organization to leverage IoT services.
This book centers on how to start building custom solutions using the IoT hub or the pre-configured solution of Azure IoT suite. As a developer, you will learn how to connect multiple devices to the Azure IoT hub, develop, manage the IoT hub service and integrate the hub with the cloud. We cover REST APIs along with HTTP, MQTT and AMQP protocols. It also helps you learning Pre-Configured IoT Suite solutions.
Moving ahead, we cover topics like process device-to-cloud messages and cloud-to-device messages using .Net-Direct methods and device management-Query Language, Azure IoT SDK for .Net, creating and managing, Securing IoT hub, IoT Suite and many more.
We will use Windows 10 IoT core, Visual Studio, universal Windows platform. In the end, we take you through IoT analytics and present a demo of connecting a real device with Azure IoT.
