Part of the Computer Communications and Networks book series (CCN)


The D-Grid is a German national academic Grid initiative, which has been established in 2004. Since then, a variety of resource providers offer resources and services to a large and heterogeneous group of user communities. First, this chapter describes in detail the D-Grid e-Infrastructure as it is operated today. Apart from a brief historical digression, D-Grid’s organizational structure and its infrastructure are introduced, complemented by the description of two example user communities. Based on the current state, this chapter then provides a discussion on how D-Grid’s future may look like with virtualization and Cloud computing striding ahead. To this end, a prototype system with coexisting Grid and Cloud middleware is introduced, challenges at resource level are identified, and possible solutions are highlighted. Furthermore, the integration of state-of-the-art service level management, which enables D-Grid providers to guarantee distinct service levels, is discussed.
