What type of cloud service model offers applications over the internet?

Software as a Service (SaaS) is the correct answer because it specifically refers to a cloud computing service model that delivers software applications over the internet. In this model, users can access and use software applications through a web browser without the need for installation or maintenance on their local devices. SaaS typically operates on a subscription basis, enabling businesses and individual users to utilize the software without worrying about underlying infrastructure or platform management.

SaaS applications are hosted on cloud servers managed by the service provider, simplifying access and functionality across various devices and locations. Examples of SaaS include applications like Google Workspace, Microsoft Office 365, and Salesforce, which illustrate how users engage with software strictly through internet access, highlighting the model's convenience and ease of use.
