Who is responsible for decommissioning end-of-life underlying storage devices that are used to host data on AWS?

Explanations:

Customers are responsible for managing the data they store on AWS services, but they do not have access to the physical hardware. Therefore, they are not responsible for decommissioning storage devices.

AWS is responsible for the physical infrastructure that supports its services, including the decommissioning of end-of-life storage devices. This is part of the shared responsibility model where AWS manages the “infrastructure of the cloud.”

The account creator is simply the individual who initially created the AWS account. They do not have any special responsibility for the physical infrastructure.

The auditing team may verify that decommissioning procedures are in place and followed, but they do not perform the actual decommissioning.
