Which service model in cloud computing provides software applications over the internet?

The service model in cloud computing that provides software applications over the internet is Software as a Service (SaaS). This model enables users to access and use software applications hosted on the cloud without the need for installation or maintenance on local devices. SaaS applications are typically delivered through a web browser, allowing for easy access from various devices and locations.

In addition, SaaS eliminates the complexities associated with traditional software installations, such as hardware requirements, software upgrades, and security management, as these tasks are handled by the service provider. This allows users to focus on utilizing the software for their business needs rather than managing the underlying infrastructure or platform.

The other models, while important, address different layers of the cloud computing stack. Platform as a Service (PaaS) provides a platform for developers to build, deploy, and manage applications without dealing with the complexities of managing the underlying hardware and software. Infrastructure as a Service (IaaS) offers virtualized computing resources over the internet, such as servers and storage, giving users control over the infrastructure but not delivering software applications directly. Network as a Service (NaaS) focuses on providing network services rather than software applications.

Therefore, SaaS stands out as the primary model designed for delivering software applications to
