Correct Answer:
D
Infrastructure-as-a-Service, commonly referred to as simply ''IaaS,'' is a form of cloud computing that delivers fundamental compute, network, and storage resources to consumers on-demand, over the internet, and on a pay-as-you-go basis. IaaS enables end users to scale and shrink resources on an as-needed basis, reducing the need for high, up-front capital expenditures or unnecessary ''owned'' infrastructure, especially in the case of ''spiky'' workloads. In contrast to PaaS and SaaS (even newer computing models like containers and serverless), IaaS provides the lowest-level control of resources in the cloud.
