With AWS IoT Device Management, you can register your connected devices individually or in bulk, and easily manage permissions so that devices remain secure. You can also organize your devices, monitor and troubleshoot device functionality, query the state of any IoT device in your fleet, and send firmware updates over-the-air (OTA).

You will be charged for the AWS services that you are using in the workshop. For exploring AWS products take a look at the AWS Free Tier.
