Résumé
Containerized environments are ideal for running scientific workflows because they offer a flexible and easily instantiated setting. Although there are solutions for executing workflows in containerized environments, these were not designed to handle scientific workflows, especially those with confidentiality requirements. Non-compliance with these requirements allows malicious users to infer unpublished results or the workflow structure itself. Data dispersion and encryption can be adopted in this context, but not independently of workflow scaling, as this can increase the total execution time or the associated financial cost. In this paper, we present Okinawa, a heuristic for executing workflows in containerized environments with confidentiality constraints.
