The computing challenges at HL-LHC require fundamental changes to the distributed computing models that have served experiments well throughout LHC. ATLAS planning for HL-LHC computing started back in 2020 with a Conceptual Design Report outlining various challenges to explore. This was followed in 2022 by a roadmap defining concrete milestones and associated effort required. Today, ATLAS is proceeding further with a set of "demonstrators" with focussed R&D in specific topics described in the roadmap. The demonstrators cover areas such as optimised tape writing and access, data recreation on-demand and the use of commercial clouds. This paper presents an overview of the demonstrators, detailing the plans, timelines and expected impact of the work.
