KubeCon + CloudNativeCon Europe 2025 · Session
Dennis Marttinen's KubeCon EU talk, "Thousands of Virtual Kubelets: 1-to-1 Mapping a Supercomputer To Kubernetes With... Superetes," delves into the increasingly critical convergence of High Performance Computing (HPC) and cloud environments. Marttinen, a master's student in security and cloud computing, presents **Superetes**, a novel transparent bridge designed to seamlessly integrate Kubernetes with existing Slurm-managed supercomputers. The talk highlights the growing demand for HPC resources from the artificial intelligence (AI) community and the need to make these powerful systems as accessible, secure, and resilient as cloud platforms.

This talk presents Superetes, a novel and technically robust transparent bridge that maps an entire Slurm-managed supercomputer to Kubernetes using virtual Kubelets. Beyond the clever bidirectional synchronization and firewall-resilient implementation, the speaker delivers a brutally honest assessment of traditional HPC's fundamental flaws in secure multi-tenancy and high availability. This isn't just a solution; it's a critical analysis that lays out a compelling vision for Kubernetes as the future orchestrator for supercomputing, offering a clear path to genuine cloud-native security and…
