"SaaS" stands for Software as a Service, offering software applications via the cloud rather than traditional on-premises installation. This model allows users to access software through a web browser, eliminating the need for extensive hardware and manual updates. Compared to traditional software delivery, SaaS provides benefits like flexibility, scalability, and cost-effectiveness, as users typically pay a subscription fee rather than a one-time purchase. Furthermore, SaaS solutions often come with automatic updates and integrated support, ensuring users have access to the latest features and security measures.
