Cloud computing is a model of data processing based on using services provided by a vendor (an internal department or an external organisation). Functionality is understood here as a service (providing a user with added value) offered by given software (and the necessary infrastructure). This means the elimination of the necessity to buy a [software] licence or the necessity of installing software and administering it. A consumer pays for the possibility of using a service, e.g. the possibility of using a calculation spreadsheet, and does not have to purchase either the equipment or the software.
