👉 Software-as-a-Service (SaaS) computing is a cloud-based delivery model where software applications are hosted on remote servers and made available to users over the internet. Instead of installing and maintaining software locally, users access these applications through web browsers or dedicated client applications, typically on a subscription basis. This approach eliminates the need for upfront capital expenditure on hardware and software licenses, reduces maintenance costs, and allows for automatic updates and scalability. SaaS providers manage all aspects of the software, including infrastructure, security, and updates, ensuring users have access to the latest features and improvements without any direct involvement from the service provider.
