With AWS IoT Device Management, you can group your device fleet into a hierarchical structure based on function, security requirements, or any other category. You can group one device in a room, group devices together that operate on the same floor, or group all the devices that operate within a building. Then, you can use these groups to manage access policies, view operational metrics, or perform actions on your devices across the entire group. You can also automate organization of your devices with dynamic thing groups. Your dynamic thing groups will automatically add devices that meet your specified criteria and remove the devices that no longer match the criteria.
