Which cloud service model would you use if you want to run your own code on infrastructure you rent from a provider?

• A. IaaS
• B. PaaS
• C. SaaS
• D. DaaS

Answer: (A)

You want the level of control where you manage your own operating system, runtimes, and applications, while the provider handles the physical hardware and virtualization. That’s Infrastructure as a Service. With IaaS you rent virtual machines, storage, and networking, and you install and run your own OS and code on those resources. The provider takes care of the underlying hardware, virtualization layer, and basic security at the infrastructure level, but you’re responsible for the software stack above it.

In a Platform as a Service setup, the platform manages the runtime and OS for you, so you deploy code but don’t control the underlying environment. In Software as a Service, you consume a ready-made application hosted by the provider, with no code or runtime management on your end. DaaS isn’t the standard model for running your own code on rented infrastructure.
