Question
Tailwind Traders has recently migrated to Azure cloud services. The development departments are currently working on new loT applications and require a managed service hosted in the cloud that acts as a central message point for bi-directional communication between their loT application and the devices it manages. Which of the following will provide this solution?
A. Azure Sphere
B. Azure loT Hub
C. Azure loT Central
Answer
B. Azure loT Hub
Explanation
You can use Azure loT Hub to build loT solutions with reliable and secure communications between millions of loT devices and a cloud-hosted solution backend.
The correct answer is B. Azure IoT Hub.
Azure IoT Hub is a managed service hosted in the cloud that acts as a central message hub for communication between an IoT application and its attached devices. It supports device-to-cloud and cloud-to-device messaging, device management, authentication, and scaling. Azure IoT Hub can be used to connect millions of devices and their backend solutions reliably and securely.
Azure Sphere is a secured IoT platform for building solutions that start in silicon and extend through the OS and the cloud. It comprises a secured, connected, crossover microcontroller unit (MCU), a custom high-level Linux-based operating system (OS), and a cloud-based security service that provides continuous, renewable security. Azure Sphere is not a messaging service, but it can use Azure IoT Hub to communicate with the cloud.
Azure IoT Central is an IoT application platform as a service (aPaaS) that reduces the burden and cost of developing, managing, and maintaining IoT solutions. It provides a ready-made UX and API surface for connecting and managing devices at scale, delivering reliable data for business insights. Azure IoT Central is not a messaging service, but it uses Azure IoT Hub under the hood to connect devices to the cloud.
