The possibilities of IoT are transformative. It empowers businesses to adopt data-driven approaches, which allows them both to create new business models as well as allow for the optimization and modification of existing operations. IoT collects data from multiple devices. Therefore, there are many intricacies to consider when it comes to data collection. IoT device monitoring is vital. It is crucial for maintaining security and monitoring connected devices.
IoT device control has become more crucial as IoT adoption increases across industries. IoT Device Management is an essential requirement for the successful deployment an enterprise's IoT Solution.
What is IoT Device Management, you ask?
IoT Device Management covers processes such as registration, configuration, provisioning, maintenance, and monitoring connected devices. IoT device administration is included in the offerings of all the major cloud providers such as AWS IoT Hub or Google Cloud IoT.
Their device management solutions allow IoT solutions providers authenticate, provide, control, configure and maintain IoT devices.
How does IoT Device Management operate?
Here are the steps to IoT Device management

Step 1: Register devices
You might find many billions more smart devices connected to the internet. But, each device needs to be connected first to the internet. Registering your device is the first thing you should do.
AWS IoT is an example of this. Each device is called a "thing". A thing can be either an actual device or a representation of one. You can either register one or more devices at a given time, or you can have multiple devices registered depending on your requirements.
You can register only one sensor at the same time if it is a temperature sensor. You may need to register multiple sensors if you are responsible for managing a fleet of self driving cars.
If you use the AWS IoT platform, you have the ability to create groups in the IoT devices registry. You can create groups in the registry to allow you to consolidate devices so that you can issue similar commands to different devices.
Step 2: Configure devices and provide them
After you register your device, you must provision it so that it is ready for use. Let's examine the setup and provisioning process for a device that uses the AWS IoT Platform.
The following resources will be required to provision your device.
A IoT policy
An IoT policy refers to a document that outlines whether your device is allowed to send and receive data from other locations. Without the policy, your device can't send and receive data. To provision a device into the IoT Core, you must link the IoT policies to the device certificates.
An X.509 Certification
It is a digital certification that leverages the X.509 Public Key Infrastructure to validate that the certificate certifies that the device has the correct key. AWS may issue an X.509 certificate to an existing IoT item or device. A certificate must first be copied to the item you have created for your device.
Your IoT Device/Sensor
If you only have one device that you want to provision in IoT, this process may be able to work. For many devices, the process is slow and time-consuming. AWS offers a way to do this automatically for many devices.
Step 3 - Send and Receive Data
Two protocols enable you to receive and transmit data from IoT devices real-time.
MQTT (Male to Device Transfer Protocol): This lightweight sub/pub protocol is used where there is no internet bandwidth and data transfer is difficult. It is a device to-device protocol, and is widely used in IoT solution.
HTTP: It is a protocol for data transmission over the internet. It supports more information that MQTT, and is not recommended for low-bandwidth locations.
Step 4: Data Analysis
The final step in the analysis of data from IoT devices is to apply computation and take action on it. Here are the steps to calculate data using:
Execution Workflow
A workflow is needed to manage the data that IoT devices collect. A notification should be sent to users immediately if the temperature below which a product is kept should be reduced. An IoT system that is well-designed can make it easier to execute your tasks.
