Software as a Service is a cloud computing delivery model
wherein software is centrally hosted and is licensed on a subscription basis.
In SaaS, the software is delivered to the end-users on an on-demand basis over
the Internet. Clients can easily gain access to these centrally hosted software
applications via a web browser, and that too without worrying about intricate
software and hardware management. This
software distribution has become highly prevalent in today’s IT dependent landscape,
registering significant growth in just couple of years.
Almost all kind of business applications including payroll processing software, accounting, collaboration, customer relationship management (CRM), enterprise resource planning (ERP), management information systems (MIS), and content management (CM) are leveraging this software delivery model.
Furthermore, SaaS has the capability to cutback to reduce IT support costs, which is why businesses of all shapes and sizes are looking forward to outsource hardware and software maintenance and support to the SaaS vendor.
