WLCG Strategy 2024-2027

The Worldwide LHC Computing Grid (WLCG) is the global infrastructure developed and operated over the last two decades that provides the computing infrastructure for the processing and analysis of data from the LHC experiments. The WLCG Collaboration comprises the sites being part of the infrastructure and the LHC experiments1, with a thin management layer. The success of WLCG has relied on innovation, leadership, collaboration, agility, and the confidence of the community and funders to commit to the endeavour. The future brings new challenges in terms of scale, technology, funding, sustainability, and the growth of other related communities. Within this context, WLCG must develop a strategy to enact over the next four years to prepare for HL-LHC Run-4 that will bring a step change in the amount and complexity of the data that will need to be processed.
