In which cloud service model is the customer only responsible for the data?

In the Software as a Service (SaaS) model, the customer is primarily responsible for managing their own data while the service provider takes care of the underlying infrastructure, platform, and applications. This model is designed to offer users access to software applications via the internet, allowing them to use the software without having to install or maintain the applications themselves.

SaaS provides various advantages, including automatic updates, scalability, and a reduced burden on IT resources since the infrastructure and software maintenance are handled by the provider. As a result, customers focus mainly on managing the data they input, use, and store within the application, making it a suitable choice for organizations looking to minimize their operational complexities while benefiting from robust software functionalities.
