On Demand Services

On-demand service delivery model is a passive service delivery model. With it it depends entirely upon the discretion of a client to determine the need for a given service and to initiate its performance. While such an approach is often implied to design or build of a new project, with a production system it is possible that a certain problem is not recognized in time and persists for a long period of time.
