KubeCon + CloudNativeCon India 2026

This talk tackles the global GPU shortage and a critical cloud-native reality in batch workload scheduling: "Kueue Quota reserved" does not equal "Capacity available". For production inference, this distinction determines whether workloads succeed or remain stuck indefinitely.

The session explores transcending regional silos using MultiKueue to manage a global federation of worker clusters. Moving beyond basic setup, the speakers address the "Quota vs. Datacenter Capacity" dilemma. They reveal a critical gap discovered through experiments: workloads becoming stranded in regions with exhausted capacity despite available quotas.

The speakers share their collaboration with the community to resolve these scheduling gaps (Issue #8089). This talk demonstrates the configuration aspects of Admission Checks and provisioning classes in Multikueue to force the scheduler to "hunt" for actual capacity in worker clusters across regions rather than relying solely on user-provided quota.
