Which of the following is a difference between cloud computing and visualization when implementing IaaS?

In cloud computing (IaaS), the cloud provider maintains the underlying hardware, not the customer's on-site IT staff.

Neither cloud nor virtual solutions inherently provide additional programmers; they provide infrastructure or platforms upon which applications are built by existing or hired staff.

Software licensing in cloud environments typically involves subscription-based models or licenses bundled with the service, not usually boxed retail versions.

Cloud computing platforms, particularly for IaaS, heavily rely on virtualization to provision and manage virtual machines, storage, and networking resources for customers. However, virtualization, such as running a hypervisor on on-premise servers, can exist independently without offering "cloud services" (on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service).
