What does IaaS primarily focus on in terms of resource provisioning?

IaaS, which stands for Infrastructure as a Service, primarily focuses on providing hardware and networking resources in a virtualized environment. Through IaaS, users can access fundamental computing services such as virtual machines, storage, and networks over the internet. This allows organizations to avoid the complexities and costs associated with maintaining their own physical hardware.

The key advantage of IaaS is that it gives customers the flexibility to scale resources up or down as needed, based on their computing demands. This service model enables businesses to deploy and manage software and applications effectively while leveraging the underlying hardware provided by the IaaS vendor.

While other options involve important aspects of computing, they do not align with the core focus of IaaS. Application software pertains to software solutions that run on the infrastructure, and database management involves software to handle databases but does not emphasize the hardware aspect. Virtual environments are a component of IaaS, but they are not the primary focus, as IaaS encompasses broader hardware and networking capabilities.
