SaaS stand for Software as a Service. The term Software as a Service falls within the subject area of Cloud Computing and is sometimes accompanied by the terms Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). Unlike traditional software which comes packaged in a box (“shrink wrapped”) on CDs and needs to be installed on each user’s computer, SaaS is a software delivery model in which the software, and usually the data, are hosted “in the cloud”. This means that users can access the software via a web-browser without having the application install on their computer. For software that uses or supports client specific data and information, this data is typically persisted in the cloud as well and is accessible by users after logging into their account.
Some of the more common disciplines in which SaaS has become the predominate software delivery model are accounting, customer relationship management (CRM), ernterprise resource planning (ERP), human resource management (HRM), content management systems (CMS), and collaborative software including file sharing software and project management software.
SaaS has several advantages over the more traditional “shrink wrap’ software delivery model.
