oftware as a Service (SaaS) is a cloud-based delivery model where software applications are hosted on the internet and accessed by users through a web browser. Unlike traditional software, which requires installation and maintenance on individual devices, SaaS operates on a subscription basis, typically billed monthly or annually. Users access the software via a centralized platform, often without needing to manage infrastructure, updates, or security concerns.

Key benefits of SaaS include cost-effectiveness, scalability, and ease of access. Businesses can reduce upfront costs, as they do not need to invest in hardware or software maintenance. SaaS solutions are also highly scalable, allowing companies to adjust their usage and pricing plans as their needs grow. Furthermore, SaaS applications can be accessed from any device with an internet connection, enhancing mobility and collaboration for users.
