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.
