Which cost is the company’s direct responsibility?

Explanations:

The company is responsible for the cost of application software licenses, as these are typically not included in the cloud service pricing and must be purchased separately by the company.

The cost of hardware infrastructure on AWS is the responsibility of AWS. AWS manages the physical hardware, and the company only pays for the resources (like compute, storage, etc.) they use.

The cost of power for AWS servers is part of AWS’s operational expenses. AWS manages the physical infrastructure, including power supply, and the company does not directly incur this cost.

Physical security for the AWS data center is AWS’s responsibility. AWS provides security for the data centers, and customers do not directly pay for this aspect.
