Saas
SaaS refers to a modern software delivery model where applications are centrally hosted and delivered to users via the internet.
Definition
Software as a Service (SaaS) is a cloud-centric distribution model in which a provider hosts applications on remote servers and makes them available to customers over the internet, typically through a web browser or lightweight client. Users subscribe to the service rather than installing and managing software locally, offloading infrastructure, updates, and maintenance to the provider. This model supports broad accessibility from any internet-connected device and scales with business needs. SaaS has become a dominant form of delivering business and consumer applications due to its convenience, cost predictability, and reduced IT overhead.
