Over the past quarter-century, web archive collection has emerged as a user-friendly process thanks to cloud-hosted solutions such as the Internet Archive’s Archive-It subscription service. Despite advancements in collecting web archive content, no equivalent has been found by way of a user-friendly cloud-hosted analysis system. Web archive processing and research require significant hardware resources and cumbersome tools that interdisciplinary researchers find difficult to work with. In this paper, we identify six principles - the ABCDEFs (Archive, Big data, Concurrent, Distributed, Efficient, and Flexible) - used to guide the development and design of a system. These make the transformation of, and working with, web archive data as enjoyable as the collection process. We make these objectives - largely common sense - explicit and transparent in this paper. They can be employed by every computing platform in the area of digital libraries and archives and adapted by teams seeking to implement similar infrastructures. Furthermore, we present ARCH (Archives Research Compute Hub)1, the first cloud-based system designed from scratch to meet all of these six key principles. ARCH is an interactive interface, closely connected with Archive-It, engineered to provide analytical actions, specifically generating datasets and in-browser visualizations. It efficiently streamlines research workflows while eliminating the burden of computing requirements. Building off past work by both the Internet Archive (Archive-It Research Services) and the Archives Unleashed Project (the Archives Unleashed Cloud), this merged platform achieves a scalable processing pipeline for web archive research. It is open-source and can be considered a reference implementation of the ABCDEF, which we have evaluated and discussed in terms of feasibility and compliance as a benchmark for similar platforms.
