On Demand Services

The on-demand service delivery model is a passive approach to service delivery. With this model, it depends entirely on the client’s discretion to determine the need for a given service and to initiate its execution. While such an approach is often appropriate for the design or construction of a new project, in a production system it may lead to situations where certain problems go unnoticed and persist for an extended period of time.
