What are two common cloud service models, and what does each provide?

• A. IaaS provides virtualized storage and computing resources; SaaS provides software applications delivered over the internet
• B. PaaS provides hardware; IaaS provides social media apps
• C. SaaS provides hardware resources; IaaS provides software
• D. DaaS provides networks; CaaS provides containers

Answer: (A)

In cloud computing, two common service models are IaaS and SaaS. IaaS provides virtualized computing resources such as servers, storage, and networking, so you can run your own operating systems and applications while the provider handles the underlying hardware and virtualization. SaaS delivers software applications over the internet that you use directly, with the vendor managing the software, platform, and infrastructure. The other options mix up what is provided (for example, focusing on hardware or platform-specific tools) and aren’t describing the standard two models in the way this question asks.
