Which cloud service model provides hardware resources to install your operating system?

1. IaaS

2. PaaS

3. SaaS

4. Hybrid Cloud

The correct answer is: IaaS

The correct answer is IaaS, which stands for Infrastructure as a Service. This cloud service model provides fundamental computing resources such as virtual machines, storage, and networks, allowing users the flexibility to install and manage their operating systems as needed. It delivers raw hardware resources over the internet, meaning the user has control over the operating system and any applications they choose to run. In contrast, PaaS, or Platform as a Service, offers a platform allowing users to develop, run, and manage applications without getting involved in the infrastructure. While it simplifies deployment, it does not give users the ability to install their own operating systems. SaaS, or Software as a Service, provides software applications over the internet, eliminating the need for installation or configuration of the operating system, as the software is fully managed by the service provider. The term Hybrid Cloud does not refer to a cloud service model, but rather to a computing environment that combines the use of both public and private clouds, allowing for greater flexibility and deployment options. Therefore, IaaS stands out as the model that provides the necessary hardware resources for users to install and control their own operating systems, making it the correct answer.
