There are several Grid adoption barriers identified by BEinGRID. One is that people worry about unmastered technology, another is about security policies and accounting in shared service environment.

The current IT culture is also reluctant to sharing resources and lack of standards prevents interoperability. And then, Pierre Guisset summarized, there are issues in the need for application re-architecturing, Grid-enabled

Service Level Agreements, legal issues, IPR and licensing. Within BEinGRID, these issues have been studied and general advices have been produced: business models and market models appropriate for Grid technology, reports on legal and licensing solutions have been published.

Several market entry strategies are employed by the Grid Business Experiments:

• Software as a Service (SaaS) is the most popular one.
• Software as a Product is also used: Development of specific Grid middleware that is then sold as commercial, licensed software.

ASPs strategy to offer Grid-enabled applications:

• Open Source Software as a market entry strategy is not widely used within the Grid Business experiments.
• Value Added Services: Provision of value-added services as systems integration and other consulting services is explored by several of the Business Experiments.

The popularity of SaaS is explained by Pierre Guisset to be a result of the fact that it requires zero install and zero management effort from the client. There is the possibility for pay per use, which gives the user the idea he can control his costs. But, because someone is providing the service, there is also always someone to call when things go wrong, which is a big advantage in a business setting.

An example of a successful Business experiment is the one that implemented Computational Fluid Dynamics on the Grid for the automotive industry; another one constitutes Financial Portfolio Management and a third is about Seismic Processing and Reservoir Simulation.
