Why each option
In the Infrastructure as a Service (IaaS) cloud service model, the cloud provider is responsible for managing the underlying physical infrastructure and its security.
In IaaS, while the provider maintains the physical storage infrastructure, the customer is typically responsible for the logical configuration and management of their specific storage volumes attached to virtual machines.
The customer is responsible for the installation, configuration, and patching of the operating system on virtual machines provisioned within the IaaS environment.
Maintaining the hardware refers to the physical servers, networking equipment, and storage devices that comprise the cloud infrastructure, which is a core responsibility of the IaaS provider.
While the provider manages the underlying physical network, the customer is responsible for configuring the logical network components within their virtual cloud environment, such as subnets, firewall rules, and routing for their virtual machines.
Physical security of the datacenter infrastructure involves securing the buildings, environmental controls, and physical access, which are managed exclusively by the cloud service provider.
