Which cloud service model provides software applications over the internet?

• A. SaaS
• B. PaaS
• C. IaaS
• D. Cloud Concepts

Answer: (A)

Software as a Service (SaaS) delivers software applications over the internet. The provider hosts the application, manages the underlying infrastructure, security, updates, and maintenance, and you access the software through a web browser or lightweight client. You don’t install or run the software locally or manage the hardware or runtime environment. This is different from Platform as a Service, which offers a development platform to build and deploy apps while the provider handles the runtime and infrastructure, and Infrastructure as a Service, which provides virtualized computing resources like servers and storage for you to manage. The option listed as Cloud Concepts isn’t a standard service model. Examples of SaaS include Gmail, Microsoft 365, and Salesforce.
