The SLICES-ITA infrastructure node is a combination of heterogeneous testbeds independently operated by CNR, CNIT and CINI. In the following, we provide a brief description of these testbeds. It is important to point out that, while CNR, CNIT and CINI are all members of the SLICES initiatives, only CNR participates in the SLICES-SC project. Thus, transnational and virtual access activities will primarily be supported using CNR facilities.
