SaaS
In recent years, Software as a Service (SaaS) has changed from curiosity caused concept to an accepted well known concept. A key advantage of this model is that, by cautious engineering, it is possible to influence economy of scale to decrease total cost of ownership compared to on-premises solutions. Software as a service (SaaS) is a software delivery method that provides access to software and its functions remotely as a Web-based service. It is sometimes referred to as "service(s) as a software substitute" (SaaSS) or "on-demand software". 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, DBMS software, management software, CAD software, etc.
The concept of software as a service (SaaS) took hold at a time when IT executives were getting supremely fed up with the ballooning costs of packaged enterprise software. Not only did they have to shell out thousands of dollars just for the licenses, but they also had to spend tens if not hundreds of thousands more to implement the software. There were the consulting fees. And the training costs. And the extra infrastructure that was required to run the software in addition to ongoing maintenance fees. Thus, SaaS emerged from the wreckage of botched multimillion-dollar ERP and CRM implementations as a radical alternative to traditional software licensing models. SaaS promised easier, speedier and cheaper implementations.
Advantages of SaaS:
1. SaaS deployments usually take less time than on premise software implementations simply because you’re not installing software on every user’s computer.
2. Because SaaS is easier and quicker to implement than traditional software, you can achieve ROI faster, too—provided, of course, your users adopt the software.
3. Upgrades also tend to be pretty seamless (because you haven’t customized the software), and you’re always on the most recent
