    Question

    Which cloud computing service model provides users with

    complete control over hardware resources like servers, storage, and networks?
    A Software as a Service (SaaS) Correct Answer Incorrect Answer
    B Platform as a Service (PaaS) Correct Answer Incorrect Answer
    C Infrastructure as a Service (IaaS) Correct Answer Incorrect Answer
    D Function as a Service (FaaS) Correct Answer Incorrect Answer
    E Content as a Service (CaaS) Correct Answer Incorrect Answer

    Solution

    Infrastructure as a Service (IaaS) is the foundational layer of cloud computing service models, offering virtualized computing resources over the internet. 1. Complete Control: IaaS provides users with virtualized servers, storage, and networking hardware. Users have administrative control to configure and manage these resources. 2. Scalability: Resources can be scaled up or down based on demand, making IaaS highly flexible. 3. Cost-Effective: IaaS eliminates the need for purchasing physical hardware, reducing capital expenses. IaaS serves as the backbone for hosting applications and operating systems, offering granular control while maintaining cost-efficiency. Why Other Options Are Incorrect: • A) SaaS: Provides end-user software applications over the internet but does not allow control over the underlying infrastructure. • B) PaaS: Focuses on providing a platform for developers to build applications without managing underlying hardware. • D) FaaS: A serverless model offering event-driven execution of small code blocks, without direct control over infrastructure. • E) CaaS: Refers to delivering content, not virtualized hardware resources.
