As you might have already guessed, the SaaS definition is "Software as a Service". This type of software is being delivered online via a browser and is hosted by the software vendor or another third party. A regular monthly fee is being charged for the use. On rare ocasions there are one time payment deals. The vendor of the web-based solution delivers a service that covers all security, availability and performance standards.
