Abstract
Small credit-card-sized single-board computers, such as the Raspberry Pi, are becoming ever more popular in areas unrelated to the education of children, for which they were originally intended. So far, these computers have mainly been used in small-scale projects focusing very often on hardware aspects. We want to take single-board computer architectures a step further by showing how to deploy part of an orchestration platform (OpenStack Swift) on a Raspberry Pi cluster to make it a useful platform for more sophisticated data collection and analysis applications located at the edge of a cloud. Our results illustrate that this is indeed possible, but that there are still shortcomings in terms of performance. Nevertheless, with the next generation of small single-board computers that have been introduced recently, we believe that this is a viable approach for certain application domains, such as private clouds or edge computing in harsh environments.
