My understanding is the machine needs AWS credentials to use this. So instead of managing disk encryption keys, you have to manage AWS credentials instead. Can somebody correct me if this is wrong?

If this is the case, then this is really only useful for managing multiple disks and giving some remote control.

Quite nice since you can very easily manage aws credentials and get stuff like 2FA. Encryption Keys might be a bit trickier.
