Which cloud service model provides software that is hosted off-site and accessed by users without installation?

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

Answer: (C)

Cloud service models define who handles software, platforms, and infrastructure. Software as a Service delivers applications over the internet, hosted off-site by the provider, and accessed directly by users without installing anything on their devices. Updates, maintenance, and hosting are all managed by the provider, so you just use the software through a browser or thin client. Examples include Gmail, Salesforce, and Microsoft 365. In contrast, IaaS gives you virtualized infrastructure and you install and manage the operating system and applications yourself. PaaS provides a platform with runtime and tools for developing and deploying applications, but you still manage your apps and deployments on top of that platform. Container as a Service focuses on running and managing containers, not full software applications for end users.
