Azure IoT Hub
True or false: The IoT Hub service supports one-way communications from the device to the cloud.
False. The IoT Hub service supports communications both from the device to the cloud and from the cloud to the device. It also supports multiple messaging patterns, such as device-to-cloud telemetry, file upload from devices, and request-reply methods to control your devices from the cloud.
From a cloud-to-device perspective, IoT Hub allows for ___________________. That is, you can have either manual or automated remote control of connected devices, so you can instruct the device to open valves, set target temperatures, restart stuck devices, and so on.
command and control
_____________ builds on top of IoT Hub by adding a dashboard that allows you to connect, monitor, and manage your IoT devices.
True or false: With Azure IoT Central, you can watch the overall performance across all devices in aggregate, and you can set up alerts that send notifications when a specific device needs maintenance. Finally, you can push firmware updates to the device.

A key part of IoT Central is the use of _____________. By using these, you can connect a device without any service-side coding. IoT Central uses the templates to construct the dashboards, alerts, and so on.
device templates
__________ creates an end-to-end, highly secure IoT solution for customers that encompasses everything from the hardware and operating system on the device to the secure method of sending messages from the device to the message hub. It has built-in communication and security features for internet-connected devices.
What are the 3 parts of Azure Sphere?
- The first part is the Azure Sphere micro-controller unit (MCU), which is responsible for processing the operating system and signals from attached sensors. The following image displays the Seeed Azure Sphere MT3620 Development Kit MCU, one of several different starter kits that are available for prototyping and developing Azure Sphere applications.
- The second part is a customized Linux operating system (OS) that handles communication with the security service and can run the vendor’s software.
- The third part is Azure Sphere Security Service, also known as AS3. Its job is to make sure that the device has not been maliciously compromised. When the device attempts to connect to Azure, it first must authenticate itself, per device, which it does by using certificate-based authentication. If it authenticates successfully, AS3 checks to ensure that the device hasn’t been tampered with. After it has established a secure channel of communication, AS3 pushes any OS or approved customer-developed software updates to the device.de
What IoT hub production can your programmers use create a customized set of management tools and reports?
IoT Hub RESTful API

IoT Central
True or false: IoT Sphere integrates with many different Azure products, including IoT Hub, to create a dashboard with reports and management features.
False. IoT Central integrates with many different Azure products, including IoT Hub, to create a dashboard with reports and management features.
What are key criteria that would lead to deciding which IoT product to use?
- Is it critical to ensure that the device is not compromised? Not in every case. Manufacturers and customers would rather not have their devices to be maliciously compromised and used for nefarious purposes, however in some cases it’s more critical to ensure the integrity than others. Do I need a dashboard for reporting and management?
- Your next decision will be the level of services you require from your IoT solution. If you merely want to connect to your remote devices to receive telemetry and occasionally push updates, and you don’t need any reporting capabilities, you might prefer to implement Azure IoT Hub by itself. Your programmers can still create a customized set of management tools and reports by using the IoT Hub RESTful API. However, if you want a pre-built customizable user interface with which you can view and control your devices remotely, you might prefer to start with IoT Central.

_____________ is a term used to describe an execution environment that’s set up and managed for you. You merely specify what you want to happen by writing code or connecting and configuring components in a visual editor, and then specify the actions that trigger your functionality, such as a timer or an HTTP request. Best of all, you never have to worry about an outage, your code can scale instantly to meet demand, and you pay based only on the actual usage of your code.
Serverless computing
____________________ is a cloud-hosted execution environment that runs your code but abstracts the underlying hosting environment.
serverless computing
True of false: With serverless computing, the key idea is that you’re not responsible for setting up or maintaining the server. You don’t have to worry about scaling it when there’s increased demand, and you don’t have to worry about outages. The cloud vendor takes care of all maintenance and scaling concerns for you.
True
With _____________, you configure your apps to respond to events. An event could be a REST endpoint, a periodic timer, or even a message received from another Azure service. The app runs only when it’s triggered by an event. Scaling and performance are handled automatically, and you’re billed only for the resources you use. You don’t even need to reserve resources.
serverless computing
_____________ is ordinarily used to handle back-end scenarios. In other words, it is responsible for sending messages from one system to another, or processing messages that were sent from other systems. It’s not used for user-facing systems but, rather, it works in the background.
Serverless computing
With the ____________, you can host a single method or function by using a popular programming language in the cloud that runs in response to an event. An example of an event might be an HTTP request, a new message on a queue, or a message on a timer.
Because of its atomic nature, _____________ can serve many purposes in an application’s design. These can be written in many common programming languages, such as C#, Python, JavaScript, Typescript, Java, and PowerShell.
