A cloud service model that provisions fully developed application services to users.

• A. Software as a Service (SaaS)
• B. Platform as a Service (PaaS)
• C. Cloud computing
• D. Cloud service models

Answer: (A)

Understanding which cloud service model delivers fully developed software to end users. Software as a Service provides applications hosted by a provider and accessed over the internet. The provider handles everything from the underlying infrastructure to the application maintenance, updates, and security. Users simply use the software through a web browser or lightweight client, without installing or managing the software or its environment. Examples include email, CRM, and productivity apps delivered as a service. This differs from Platform as a Service, which offers a development platform for building and deploying your own applications, not ready-made software for end users. Infrastructure as a Service gives you compute, storage, and networking resources, but you manage the operating system, middleware, and applications yourself. Cloud computing and cloud service models are broader terms, but the question points to the specific model that delivers finished software to users, which is SaaS.
