Which of the following describes a key feature of Infrastructure as a Service (IaaS)?

A key feature of Infrastructure as a Service (IaaS) is the provision of virtualized computing resources over the internet. This model allows organizations to access and manage their computing infrastructure without the need for physical hardware on-site. With IaaS, businesses can utilize resources such as VMs (virtual machines), storage, and networks on a pay-as-you-go basis, providing flexibility and scalability.

This cloud service model significantly reduces the overhead associated with maintaining physical servers and infrastructure, offering seamless access to powerful computing capabilities as needed. Organizations can quickly scale their resources up or down based on their demands, allowing for efficient management of workloads and costs.

In contrast, complete application management pertains to a different service model, typically associated with Platform as a Service (PaaS) or Software as a Service (SaaS), where the provider manages applications on behalf of the customer. The standardization of all software components is more characteristic of a controlled environment that may not apply to the highly customizable nature of IaaS. Manual deployment and oversight of hardware directly contradicts the core advantage of IaaS, where automation and virtual resources are leveraged to minimize physical intervention and enhance operational efficiency.
