WHAT ARE OFF PREMISES SERVICES ?
Ø The service (including the application and the data) resides on hardware that you do not own. This is a relative position: What is off-premises for some is on-premises for someone else. Not owning the resources implies that there is no upfront one-time acquisition cost, but, rather, that the provider is paid for the service on a recurring (subscription) basis.
Ø In the off-premises IT scenario, there are always two parties involved: the one that provides the resources (the provider) and the one that “rents” them (the user organization). We will use these terms to refer to these two roles throughout this research. In some scenarios, we will need to discuss individual users — that would be another kind of a player, which we will refer to as an “individual.” These are not members of the user organization, but rather, independently acting individuals.
Ø They, too, have the choice of running an application on their PC or off-premises (for example, in the choice between Microsoft Word or Google Docs). In all scenarios, there are always two parties: the provider and a user organization or a provider and an individual.
