Introduction
Software as a Service (SaaS) is a cloud-based software delivery model where applications are hosted by a service provider and made available to customers over the internet. Users access software on a subscription basis, without purchasing, installing, or maintaining it on local infrastructure.
SaaS products range from simple productivity tools to complex enterprise platforms integrating AI, analytics, and automation.
