Which cloud service enables on-demand access to IT resources like computing power and virtualization?

Platform-as-a-Service
Function-as-a-Service
Infrastructure-as-a-Service
Network-as-a-Service

The correct answer is: Infrastructure-as-a-Service

Infrastructure-as-a-Service (IaaS) provides on-demand access to IT resources, including computing power, storage, and virtualization, allowing users to provision and manage virtual machines and networks. This model enables users to scale resources quickly according to their needs without having to invest in physical hardware, making it a flexible and cost-effective option for businesses. IaaS is particularly beneficial for organizations that require control over their IT infrastructure while still being able to leverage the benefits of cloud computing, such as easy management and minimal overhead. In contrast, Platform-as-a-Service (PaaS) focuses more on providing a platform and environment for developers to build, deploy, and manage applications without concerning themselves with the underlying infrastructure. Function-as-a-Service (FaaS) is a serverless computing option where developers can execute code in response to events without managing servers, and Network-as-a-Service (NaaS) primarily offers network services and resources, such as bandwidth and connectivity, rather than focusing on computing power directly. Hence, IaaS specifically aligns with the requirement for on-demand access to computing resources and virtualization.
