Which model allows companies to control configurations while using hardware provided by a cloud vendor?

The model that allows companies to control configurations while using hardware provided by a cloud vendor is Infrastructure as a Service (IaaS). IaaS provides virtualized computing resources over the internet, including virtual machines, storage, and networks, all managed by the cloud provider. This model gives organizations the flexibility to configure and manage their operating systems, applications, and storage.

With IaaS, companies retain control over their server environments, granting them the ability to install and run any software they choose, configure the operating system settings, and manage security policies tailored to their specific business requirements. This level of control contrasts with other cloud service models where the provider manages more of the underlying infrastructure, limiting the user's ability to control configurations.

In comparison, Platform as a Service (PaaS) abstracts the hardware and operating system further, focusing on providing a platform for developers to build applications without managing the underlying infrastructure. Software as a Service (SaaS) offers complete applications hosted by the provider, with users having little to no control over the infrastructure or configuration options. Network as a Service (NaaS) specifically relates to network services rather than broader infrastructure control.

Thus, IaaS is the ideal choice for organizations needing significant control and flexibility while leveraging
