The presentation discusses the importance of resource management in Kubernetes and highlights new features and enhancements in the ecosystem, such as the Container Device Interface (CDI) and Cgroups V2.
  • The CDI allows for sharing of GPUs and devices across different containers and pods, as well as dynamic partitioning and mixing and matching of devices.
  • Topology-aware scheduling is not the only use case for Node Resource Information (NRI) plugins, and top-level attributes can be used for other capabilities as well.
  • Cgroups V2 provides new resource management capabilities, such as memory QoS and PSI metrics, and there are plans to explore i/o isolation and network QoS guarantees.
  • The speaker encourages feedback from the audience on resource management challenges and desired features.
