Software On-Demand: Lowering the TCO of Business Systems
Software on-demand vendors, such as Salesforce.com, Netsuite, and Employease, deliver software applications as a service instead of selling them on a license basis. This report summarizes the history and basic concepts of software on-demand and analyzes its potential to radically reduce the total cost of ownership for software buyers and the operational costs of software vendors. It also outlines the challenges that software on-demand faces in gaining widespread adoption.
