Editor's Notes

  • #3: Use of the internet is now common-place, with bits flowing all day long. Lets 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. Well 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 componibilit dei servizi offerti da Azure (anche di terze parti) 竪 la carta vincente per implementare soluzioni che si evolvono nel tempo. Azure IoT Suite 竪 un ottimo modo per capire e sperimentare una soluzione IoT chiavi in mano che pu嘆 essere facilmente adattata ad una soluzione reale.
