SAAS is an acronym for Software as a service .It is basically a method wherein a software can be used from a web server remotely.This service is mainly used by medium scale organizations since the amount paid is usually less than that of a licenced software.Users accessing this service would have to pay a fee and thereafter renew it every month.
The main advantage of using this service is that users would not require installing additional hardware since the application is hosted remotely.Its also eliminates the need for organizations to install or configure applications as well as upgraded system’s hardware or software.
