Which cloud service model allows users to access cloud applications but does not enable the user to manage the cloud infrastructure or the applications?

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

Answer: (C)

Access to software applications delivered over the cloud without managing the underlying hardware or software stack is Software as a Service. In this model, the provider hosts the application, handles maintenance, security, updates, and scalability, and you simply sign in and use the software through a browser or lightweight client. You typically focus on your data and settings, not on the infrastructure or the application’s code or runtime. Why this fits best: you’re not responsible for servers, storage, networks, or operating systems, nor for the software’s deployment and upkeep. In contrast, IaaS puts you in control of virtual machines, storage, and networks (you manage the OS and applications you install). PaaS offers a platform to develop and deploy your own apps, with the provider managing the runtime and infrastructure. DaaS delivers a virtual desktop environment rather than individual cloud applications, so it’s more about the desktop experience than software-as-a-service applications.
