Which cloud service model delivers application software to subscribers on-demand over the internet?

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

Answer: (C)

Software as a Service delivers applications over the internet on demand. In this model, the software runs in the provider’s cloud, and you access it through a web browser or lightweight client without installing it locally. The vendor handles hosting, scaling, maintenance, updates, and security, so you can focus on using the tool to get work done. This is what people mean by subscribers getting application software on demand over the internet. This differs from infrastructure as a service, which provides raw computing resources like virtual machines and storage for you to install and manage your own operating system and applications. It also differs from platform as a service, which offers a development platform and tools to build and deploy your own apps, rather than providing a ready-to-use software solution. Identity as a service focuses on authentication and identity management rather than delivering full application software. So, the option that best matches delivering application software to subscribers on-demand over the internet is the software as a service model.
