Internet of everything: let's talk about IoT and Azure - DotNet Conf 2018
0 likes170 views
The document explores Internet of Things (IoT) concepts, particularly focusing on integrating devices with Microsoft Azure using various tools like .NET Core, Azure Sphere, and Cognitive Services. It includes code snippets for managing GPIO pins on Raspberry Pi and demonstrates how to set up and train a Language Understanding Intelligent Service (LUIS) app for home automation. Additionally, it provides resources and links for further exploration of IoT solutions and Azure services.

Editor's Notes
- #3: Use of the internet is now common-place, with bits flowing all day long. Let’s review the use of Azure cloud technologies and how we can use those services with all of the gadgets, appliances, and mobile devices available to us. We’ll learn how to use Azure services with some of these devices and how Internet of Things (IoT) services can be managed.
- #30: It provides and example of Languge understand for automation in iot scenarios
- #47: La reference architecture fornisce linee guida che debbono essere adattate allo scenario specifico. La componibilità dei servizi offerti da Azure (anche di terze parti) è la carta vincente per implementare soluzioni che si evolvono nel tempo. Azure IoT Suite è un ottimo modo per capire e sperimentare una soluzione IoT chiavi in mano che può essere facilmente adattata ad una soluzione reale.
