What does SaaS stand for?

SaaS stands for Software as a Service. This model allows users to access software applications over the internet on a subscription basis, rather than purchasing and installing them on individual devices. With SaaS, software is hosted in the cloud and managed by the service provider, which means that users can access applications from anywhere with an internet connection, and they do not have to worry about the underlying infrastructure or maintenance.

This model offers various benefits, including reduced costs, scalability, automatic updates, and ease of collaboration, as multiple users can access the same application simultaneously. In contrast, the other choices represent different types of cloud services but do not describe the SaaS model specifically. For instance, Storage as a Service refers to cloud-based storage solutions, Security as a Service focuses on providing security measures through the cloud, and System as a Service does not correspond to any widely recognized model in cloud computing.
