Which cloud service model allows users to rent virtualized hardware resources over the internet?

• A. Platform as a Service (PaaS)
• B. Software as a Service (SaaS)
• C. Infrastructure as a Service (IaaS)
• D. Function as a Service (FaaS)

Answer: (C)

Infrastructure as a Service (IaaS) is the correct answer because this model provides virtualized computing resources over the internet. IaaS enables users to rent virtual machines, storage, and networks as needed without the necessity to manage physical hardware. This offers great flexibility, allowing organizations to scale their IT resources dynamically based on demand, while also shifting the responsibility for hardware maintenance to the cloud provider. In contrast, Platform as a Service (PaaS) offers a platform that allows developers to build, deploy, and manage applications without dealing with the underlying infrastructure. Software as a Service (SaaS) provides software applications over the internet on a subscription basis, removing the need for local installation and maintenance. Function as a Service (FaaS) is a coding solution that allows users to run code in response to events without having to manage the server infrastructure. Each of these models serves a different purpose within the cloud ecosystem, but IaaS specifically focuses on providing the foundational infrastructure as a service.
