Explanation
IaaS (Infrastructure as a Service) provides virtualized compute, storage, and networking resources, giving customers the highest level of control and autonomy among the three cloud service models (IaaS, PaaS, SaaS). Customers manage the OS, middleware, and applications, while the provider manages the physical hardware. This autonomy and control over the infrastructure layer is IaaS's defining characteristic. Answer C (responding to demand spikes) is a general cloud elasticity benefit shared by all models. Answer D (simple application integration) better describes PaaS or SaaS. Answer B (remote application performance) is not specific to IaaS. Compared to PaaS and SaaS, IaaS intentionally gives more control at the cost of more management responsibility.
