Describe Core Solutions and Management Tools Flashcards
________ enables devices to gather and then relay information for data analysis. It consists of smart devices that are equipped with sensors that collect data.
IoT
____________ is the ability of devices to garner and then relay information for data analysis.
IoT Internet of Things
___________ is a fully managed global IoT SaaS solution that makes it easy to connect, monitor, and manage IoT assets at scale.
Azure IoT Central
_____________ is a managed service hosted in the cloud that acts as a central message hub for bi-directional communication between IoT applications and devices it manages.
Azure IoT Hub
_________ is a secured, high-level application platform with built-in communication and security features for Internet connected devices.
Azure Sphere
Use _________to build IoT solutions with reliable and secure communications between millions of IoT devices and a cloud-hosted solution back end. With it, you can connect virtually any device.
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.
True
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
What IoT product would you use if you wanted a pre-built customizable user interface with which you can view and control your devices remotely? With this solution, you can control a single device or all devices at once, and you can set up alerts for certain conditions, such as a device failure.
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.
When security is a critical consideration in your product’s design, what is the best IoT product, which provides a comprehensive end-to-end solution for IoT devices?
Azure Sphere
True or false: Azure Sphere ensures a secure channel of communication between the device and Azure by controlling everything from the hardware to the operating system and the authentication process. This ensures that the integrity of the device is uncompromised. After a secure channel is established, messages can be received from the device securely, and messages or software updates can be sent to the device remotely.
True
_____________ provides a complete solution for scenarios where security is critical.
Azure Sphere
A company wants to build a new voting kiosk for sales to governments around the world. Which IoT technologies should the company choose to ensure the highest degree of security?
- IoT Hub
- IoT Central
