The emergence of new opportunities in AI, networking, as well as edge computing and IoT creates the potential for new avenues of exploration in science but at the same time challenges our understanding of the role and shape of infrastructure. An effective exploration of the edge to cloud continuum requires research infrastructure where those challenges can be investigated, and where new solutions and disruptive ideas can be developed, deployed, tested, and shared. Such infrastructure has to not only support a diversity of hardware configurations, deployments at scale, as well as deep reconfigrability so that a wide range of experiments can be supported – but also mechanisms and services that will allow the community to share repeatable digital artifacts so that new experiments and results can be easily replicated and help enable further innovation.

This type of research infrastructure (RI) has been implemented in systems like Chameleon, SLICES, FABRIC, or the PAWR testbeds, many of which address distinct, if overlapping, aspects of this problem. This workshop will provide a forum for the RI designers, engineers, and users to discuss emergent use cases and modes of usage; RI solutions and and operations; features that support research in the computing continuum; user interfaces and usability; experimental support for reproducibility; building and sustaining RI user communities; as well as evaluating and sustaining RI.
