What is the role of the cloud vendor in a SaaS model?

In a Software as a Service (SaaS) model, the cloud vendor primarily takes on the responsibility of administering and updating the software. This means that the vendor manages the entire software stack, from installation to ongoing maintenance, ensuring that users always have access to the latest features and security updates without needing to perform these tasks themselves.

This model is beneficial because it alleviates the burden of software management from the end-users or organizations, which can focus on their core business processes instead of IT tasks. The vendor also ensures the application is available over the internet, providing accessibility to users from various devices while also handling data storage, backup, and security measures relevant to the software environment.
