True or False: The customer maintains responsibility for the OS in an IaaS model.

In an Infrastructure as a Service (IaaS) model, the customer is indeed responsible for managing the operating system (OS) and any applications that run on the infrastructure provided by the service provider. IaaS offers virtualized computing resources over the internet, such as virtual machines, storage, and networking. This means that while the cloud provider takes care of the physical hardware, network, and data center operations, the customer maintains the control and responsibility for the OS, middleware, and any applications they deploy on that infrastructure.

This model allows customers to customize their environments to fit their specific needs while still benefiting from the scalable and flexible resources that IaaS offers. Therefore, it is accurate to state that the customer retains the responsibility for the OS in an IaaS deployment, which aligns with best practices for managing cloud-based resources.
