      abstract     = {In a geo-distributed computing infrastructure with
                      heterogeneous resources (HPC and HTC and possibly cloud), a
                      key to unlock an efficient and user-friendly access to the
                      resources is being able to offload each specific task to the
                      best suited location. One of the most critical problems
                      involves the logistics of wide-area, multi-stage workflows
                      that move back and forth between multiple resource
                      providers. We envision a model where such a challenge can be
                      addressed enabling a “transparent offloading” of
                      containerized payloads using the Kubernetes API primitives
                      creating a common cloud-native interface to access any
                      number of external hardware machines and type of backends.
                      Thus we created the interLink project, an open source
                      extension to the concept of Virtual-Kubelet with a design
                      that aims for a common abstraction over heterogeneous and
                      distributed backends. interLink is developed by INFN in the
                      context of interTwin, an EU funded project that aims to
                      build a digital-twin platform (Digital Twin Engine) for
                      sciences, and the ICSC National Research Center for High
                      Performance Computing, Big Data and Quantum Computing in
                      Italy. In this talk we first provide a comprehensive
                      overview of the key features and the technical
                      implementation. We showcase our major case studies, such as
                      the scale-out of an analysis facility, and the distribution
                      of ML training processes. We focus on the impacts of being
                      able to seamlessly exploit world-class EuroHPC
                      supercomputers with such a technology.},
