SaaS (Software as a Service) model is effective and prudent way to experience the best without paying that cost. Get the feel of the entire product by extensively using the same without actually paying for the entire product. You pay as you go.

The application is available for you and your organisation at any point of time without interruption. You will use the application from anywhere. All the services will be available online.

Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. Meanwhile, broadband service has become increasingly available to support user access from more areas around the world.

SaaS is closely related to the ASP (application service provider) and on demand computing software delivery models. IDC identifies two slightly different delivery models for SaaS. The hosted application management (hosted AM) model is similar to ASP: a provider hosts commercially available software for customers and delivers it over the Web. In the software on demand model, the provider gives customers network-based access to a single copy of an application created specifically for SaaS distribution.

Benefits of the Saas model include

  • Cost effective
  • Lesser risk of owner ship
  • Not prone to obsolete
  • No long term commitment
  • Can be construed as a product demo on cost
  • No infra structure cost
  • No manpower cost and no manpower management on Server installation
  • No software to be installed and hence no maintenance cost like antivirus etc
  • Easier administration
  • Automatic updates and patch management
  • Compatibility: All users will have the same version of software.
  • Easier collaboration, for the same reason
  • Global accessibility.
  • The traditional model of software distribution, in which software is purchased for and installed on personal computers, is sometimes referred to as software as a product.
