The project will provide gateway services for various types of user communities and for various NGI user communities. The gateway services will enable unified access to and seamless integration of the underlying networking, computing and data infrastructures and services for all the major DCI infrastructures used in Europe.

The SCI-BUS project will provide a portlet repository to the user community and an application repository for the underlying custom applications. This technology will be used by the SCI-BUS project itself to create several customised (or domain-specific) science gateways for different user communities.
