The Domino service provider administrator
The responsibilities of a service provider administrator, include maintaining both the server environment at the host site and to varying degrees, the hosted organizations.

First and foremost, the service provider administrator is responsible for setting up and maintaining xSP servers -- that is, protocol and database servers -- as well as any IBM® Lotus® Domino® clusters and network routers.

Although the hosted organization administrator can perform some of the user and group maintenance, the service provider administrator performs a significant amount of the administrative tasks required to maintain a hosted organization. At a minimum, the service provider administrator is responsible for registering and maintaining hosted organizations and controlling which applications the hosted organization uses. In addition, the service provider administrator must create and maintain a mechanism that the hosted organization's administrators use to communicate problems and issues that require the intervention of the service provider administrator.
