Which cloud service model provides the ability to scale resources based on demand?

• A. SaaS
• B. PaaS
• C. IaaS
• D. FaaS

Answer: (C)

The Infrastructure as a Service (IaaS) cloud service model provides the ability to scale resources based on demand effectively. IaaS gives users the fundamental building blocks of computing, such as virtual machines, storage, and networks, allowing them to scale these resources up or down as needed to accommodate changes in workload. This flexibility is essential for businesses that experience variable demand, as it helps manage costs and ensures that resources are available when required. IaaS enables users to provision and manage their own resources in a cloud environment, meaning they can quickly ramp up infrastructure during peak times or reduce it during lulls without the need for significant capital investment in physical hardware. This on-demand resource allocation is a core feature of IaaS and is a primary reason many organizations choose this model for their cloud infrastructure needs.
