SaaS (Software as a Service)

Short for Software as a Service, SaaS is a software delivery method that provides access to software and its functions remotely as a Web-based service. Software as a Service allows organizations to access business functionality at a cost typically less than paying for licensed applications since SaaS pricing is based on a monthly fee. Also, because the software is hosted remotely, users don't need to invest in additional hardware. Software as a Service removes the need for organizations to handle the installation, set-up and often daily upkeep and maintenance. Software as a Service may also be referred to as simply hosted applications.

Using SaaS instead of using individual computers

Benefits

- Time saving
- Easier to update
- No need for custom installations (due to the fact that the software is run on the server)


Limitations
- Security compromised (all data is stored in one location)
- Dependent on one piece of hardware
