      abstract     = {PUNCH4NFDI, funded by the Germany Research Foundation
                      initially for five years, is a diverse consortium of
                      particle, astro-, astroparticle, hadron and nuclear physics
                      embedded in the National Research Data Infrastructure
                      initiative. In order to provide seamless and federated
                      access to the huge variety of compute and storage systems
                      provided by the participating communities covering their
                      very diverse needs, the Compute4PUNCH and Storage4PUNCH
                      concepts have been developed. Both concepts comprise
                      state-of-the-art technologies such as a token-based AAI for
                      standardized access to compute and storage resources. The
                      community supplied heterogeneous HPC, HTC and Cloud compute
                      resources are dynamically and transparently integrated into
                      one federated HTCondorbased overlay batch system using the
                      COBalD/TARDIS resource meta-scheduler. Traditional login
                      nodes and a JupyterHub provide entry points into the entire
                      landscape of available compute resources, while container
                      technologies and the CERN Virtual Machine File System
                      (CVMFS) ensure a scalable provisioning of community-specific
                      software environments. In Storage4PUNCH, community supplied
                      storage systems mainly based on dCache or XRootD technology
                      are being federated in a common infrastructure employing
                      methods that are well established in the wider HEP
                      community. Furthermore existing technologies for caching as
                      well as metadata handling are being evaluated with the aim
                      for a deeper integration. The combined Compute4PUNCH and
                      Storage4PUNCH environment will allow a large variety of
                      researchers to carry out resource-demanding analysis tasks.
                      In this contribution we will present the Compute4PUNCH and
                      Storage4PUNCH concepts, the current status of the
                      developments as well as first experiences with scientific
                      applications being executed on the available prototypes.},
