What cloud model gives you complete control of the operating system?

1. IaaS

2. PaaS

3. SaaS

4. CaaS

The correct answer is: IaaS

The Infrastructure as a Service (IaaS) cloud model provides users with the highest level of control over the operating system and other aspects of the infrastructure. When utilizing IaaS, you are essentially renting physical or virtualized hardware resources, such as servers, storage, and networking, from a cloud provider. This allows you to install and configure your preferred operating system, as well as manage all software and applications running on that system. With IaaS, customers have the flexibility to customize the operating environment entirely to their needs, including the installation of security measures or specific configurations that may be necessary for their applications. This model contrasts with Platform as a Service (PaaS) and Software as a Service (SaaS), where the cloud provider manages the underlying infrastructure and may impose limitations on the operating systems or applications available to the user. In PaaS, the focus is on providing a platform for application development without control over the operating system, while SaaS offers fully managed applications with no access to the underlying OS. Container as a Service (CaaS) provides container management and orchestration but also does not grant complete control over the operating system in the same manner as IaaS. Thus, IaaS stands out
