For many years, INFN has developed its own infrastructure dedicated to scientific computing. Both analysing data produced by the big experiments and theoretical simulations actually need computing power, large storage quantities, and ultra-fast networks. In general, the synergy between computing capacity and network speed is essential for creating scalable and efficient IT infrastructure. Modern computing environments require high-speed networks to enable efficient communication between distributed systems and the sharing of computational resources. INFN proposed the National Centre for Supercomputing (ICSC) that aims to develop a distributed scientific computing infrastructure, of the Data Lake kind. This will be accessible to the whole national research community, integrating and strengthening existing computing resources with funds made available by the PNRR and extending the networks able to exchange data at the speed of a terabit per second throughout the nation.
