Computing at the HL-LHC and beyond

The High-Luminosity Large Hadron Collider (HL-LHC) is set to introduce unprecedented data volumes and computational demands, necessitating significant enhancements in the current LHC computing infrastructure. We summarize efforts by the experiments to integrate high-performance computing clusters and public cloud resources into their processing frameworks. We also examine the adoption of cloud technologies for implementation of advanced service infrastructure which are finding applications in Tier 2 centers and prototyping of future analysis facilities. We highlight the crucial role of scalable networking capabilities and challenge exercises to prepare for the expected increased data throughput.
