Which cloud computing solution delivers software applications over the Internet or a local network?

The correct choice for delivering software applications over the Internet or a local network is SaaS, which stands for Software as a Service. This model allows users to access software applications hosted on the cloud, eliminating the need for individual installations on personal devices or servers. Users typically access SaaS applications through a web browser, making it convenient as there is minimal setup and management required on their part.

Examples of SaaS include applications like Google Workspace, Microsoft 365, and Salesforce, where users can utilize the software functionalities directly without needing to manage the infrastructure or the platform on which these applications run. This model is particularly popular for business applications as it supports scalability, multi-device access, and automatic updates, ensuring users are always on the latest version without additional effort.

In contrast, other cloud computing solutions like IaaS (Infrastructure as a Service) provide virtualized computing resources over the internet, PaaS (Platform as a Service) offers a framework for developers to build and deploy applications, and DaaS (Desktop as a Service) delivers virtual desktops to users. These services may support the underlying infrastructure or application development but do not deliver software applications in the direct, user-facing manner that SaaS does.
