SAAS

Software as a service (SaaS; pronounced /sæ s/ or /sɑː s/[1]) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted.[2][3] It is sometimes referred to as "on-demand software".[4] SaaS is typically accessed by users using a thin client via a web browser. SaaS has become a common delivery model for many business applications, including office & messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization,[4] accounting, collaboration, customer relationship management (CRM), management information systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), content management (CM) and service desk management.[5] SaaS has been incorporated into the strategy of all leading enterprise software companies.[6] One of the biggest selling points for these companies is the potential to reduce IT support costs..
