With the recently started Run 3 of the LHC, enormous amounts of data are expected. It is already foreseeable that the resources provided by the Worldwide LHC Computing Grid (WLCG) will be put under a lot of stress in the coming years, especially at the start of HL-LHC in Run 4. HEP computing is therefore increasingly developing in the direction of using external non-HEP dedicated resources and thus becoming more heterogeneous. This contribution reports on the work carried out as part of the BMBF (Bundesministerium für Bildung und Forschung) funded FIDIUM (Föderierte digitale Infrastrukturen für die Erforschung von Universum und Materie) project on the dynamic and transparent integration of non-HEP resources into the existing infrastructure of the WLCG and what challenges arise in the process. The currently ongoing integration of the high performance computing (HPC) resources at Jülich Supercomputing Centre (JSC) using the resource manager COBalD/TARDIS serves as an example.
