    Question

    Which of the following cloud service models provides the

    most control over the underlying infrastructure to the user? 
    A SaaS (Software as a Service) Correct Answer Incorrect Answer
    B PaaS (Platform as a Service) Correct Answer Incorrect Answer
    C IaaS (Infrastructure as a Service) Correct Answer Incorrect Answer
    D FaaS (Function as a Service) Correct Answer Incorrect Answer
    E DaaS (Desktop as a Service) Correct Answer Incorrect Answer

    Solution

    Infrastructure as a Service (IaaS) provides users with the most control over the underlying infrastructure compared to other cloud service models. In IaaS, users can manage virtual machines, storage, networks, and operating systems directly. This level of control allows users to customize the infrastructure to meet their specific needs, making it ideal for businesses that require high flexibility and scalability. Unlike Software as a Service (SaaS) and Platform as a Service (PaaS), where the service provider manages much of the infrastructure and platform layer, IaaS gives users the freedom to deploy any operating system and applications they choose, providing a higher degree of flexibility and control. Why Other Options are Incorrect: A) SaaS (Software as a Service): This model offers software applications hosted on the cloud, with minimal control over the infrastructure. B) PaaS (Platform as a Service): PaaS provides a platform for developers to build applications without managing the underlying infrastructure, limiting control compared to IaaS. D) FaaS (Function as a Service): This model abstracts even more than PaaS, allowing users to run code without managing servers, which significantly reduces control. E) DaaS (Desktop as a Service): DaaS provides virtual desktop environments, but users have limited control over the underlying infrastructure compared to IaaS.
