It splits the problem across four components: koord-manager (control-plane reconciliation and webhooks), koord-scheduler (placement decisions via custom plugins for NUMA, devices, quotas, and reservations), koordlet (node-local QoS enforcement via Linux cgroups), and koord-runtime-proxy (optional CRI lifecycle interception). Key API contracts include QoS labels, NodeSLO (node-level policy), NodeMetric (observed usage), Reservation, Device, and ElasticQuota resources. The architecture deliberately separates scheduling intent from node-local enforcement, acknowledging that a scheduler acts on a delayed cluster view while koordlet acts on current node state, with eventual consistency across all components. ## Full article daily.dev links to this article rather than hosting it.
