  Moving from a National Grid Testbed to a Production quality Grid service for
the HEP applications requires an effective operations structure and
organization, proper user and operations support, flexible and efficient
management and monitoring tools. Moreover the middleware releases should be
easily deployable using flexible configuration tools, suitable for various and
different local computing farms. The organizational model, the available tools
and the agreed procedures for operating the national/regional grid
infrastructures that are part of the world-wide EGEE grid as well as the
interconnection of the regional operations structures with the global
management, control and support structure play a key role for the success of a
real production grid. In this paper we describe the operations structure that
we are currently using at the Italian Grid Operation and Support Center. The
activities described cover monitoring, management and support for the
INFN-GRID/Grid.It production grid (spread over more than 30 sites) and its
interconnection with the EGEE/LCG structure as well as the roadmap to improve
the global support quality, stability and reliability of the Grid service.
