What does Software as a Service (SaaS) provide to its users?

Software as a Service (SaaS) provides a comprehensive solution where the cloud provider is responsible for supplying and managing not only the software applications but also the underlying hardware, operating system, and data storage necessary for those applications to run. This allows users to access the software over the internet without needing to manage the infrastructure it runs on.

In a SaaS model, the user typically subscribes to the software and accesses it via a web browser. This setup relieves users from the burden of installation, maintenance, and updates of the software, as all those responsibilities fall under the purview of the cloud provider. This model is popular for its convenience and scalability, enabling businesses to focus on their core activities rather than on IT management.

Other options imply varying degrees of responsibility for the user or provider that do not align with the SaaS definition. For instance, some suggest that users manage certain aspects of the software or hardware, which is not characteristic of the SaaS model where the provider takes full management control of the services offered.
