n. Software applications that are rented from and maintained by a third-party vendor over the Internet. (Also apps on tap.)

Example Citation:
"Think of e-services like you would turning on the tap today. When you jump in the shower you don't think about where that water came from, what technology heated the water or how that water was delivered to your house. . . . At the end of the month a bill arrives and you pay only for the water you used. E-services will provide your business with computing resources under a utility model called an 'apps-on-tap', where you literally rent the application and only pay for as much as you use."
