S. Fiori, L. Abeni, T. Cucinotta. "RT-Kubernetes - Containerized Real-Time Cloud Computing," in Proceedings of the 37th ACM/SIGAPP International Symposium on Applied Compputing (ACM SAC 2022), April 25-29, 2022, Brno, Czech Republic (on-line event due to Covid-19).
This paper presents RT-Kubernetes, a software architecture with the ability to deploy real-time software components within containers in cloud infrastructures. The deployment of containers with guaranteed CPU scheduling is obtained by using a hierarchical real-time scheduler based on the Linux SCHED_DEADLINE policy. Preliminary experimental results provide evidence that this new framework succeeds in providing timeliness guarantees in the target responsiveness range, while achieving strong temporal isolation among containers co-located on the same physical hosts.
