Grid middleware provides the fundamental framework for the provision of Grid services. However, Grid middleware is complex software that consists of several modules. The modules for a specific grid middleware exhibit in many cases complementary features and are produced by different software providers. Thus, in order to provide a complete grid solution for business customers, it is necessary to establish a complete value network comprising all relevant suppliers. Business aspects of grid, such as business models and value networks have not been considered broadly in research yet. This paper contributes to fill this gap by describing the value network of a grid case study and by aggregating the results into a generic grid value chain.
