S5Mart Corporation is an big box department store chain headquartered in United States.
S5Mart operated 1,273 stores including 105 Super S5mart Center locations around the world. S5Mart is adopting IoT solutions across a number of applications that are improving store operations, reducing theft, increasing purchases through cross selling, enabling precise inventory management, and most importantly enhancing the consumer's shopping experience.
S5Mart is hosting their IOT solution on AWS IOT Core. S5Mart is building a custom built monitoring platform based on node.js for all the devices in AWS.
The platform basically captures the existing persistent representation of the devices.
Also the integration of IOT data collected into the application needs to be based on canonical data format like JSON.

https://docs.aws.amazon.com/iot/latest/developerguide/what-is-aws-iot.htmlS5Mart Corporation is using AWS IoT Core to host their IoT solution. They are building a custom-built monitoring platform based on node.js to capture the existing persistent representation of devices, and the integration of IoT data collected into the application needs to be based on canonical data format like JSON. In order to achieve this, they can use Device Shadow and Device Registry, which are two different services provided by AWS IoT Core.
Device Shadow is a service that provides persistent representations of devices in the AWS Cloud. It is a JSON document that is used to store and retrieve current state information for a device. Device Shadow enables applications to interact with devices even when they are offline. This is achieved by storing the last reported state of the device in the Device Shadow. When the device comes back online, it will automatically synchronize with the Device Shadow, updating the state information. Device Shadow can also be used to update the state of a device, even if it is offline. This allows applications to control the device remotely.
Device Registry is another service provided by AWS IoT Core. It is also a JSON document that is used to store and retrieve current state information for a device. The difference between Device Shadow and Device Registry is that Device Registry is used to keep track of the devices that are connected to AWS IoT Core, whereas Device Shadow is used to keep track of the state of the devices. Device Registry can be used to perform actions on devices, such as updating their metadata or deleting them from AWS IoT Core.
Therefore, the two options that best suit the requirements of S5Mart Corporation are:
