Explore innovative approaches to maximizing container workload performance and resource utilization in this conference talk from KubeCon + CloudNativeCon North America 2021. Delve into the challenges of mitigating noisy neighbors in containerized environments and discover new extension points for containerd and CRI-O. Learn about the Node Resource Interface (NRI) proposal and the evolution of dynamic resource usage optimizations in the CRI-Resource-Manager project. Gain insights into handling heterogeneous CPU resources, multi-tiered memory, caches, memory bandwidth, and block I/O usage. Understand how leveraging various metrics and hints provided by the Linux kernel can lead to improved workload performance and dynamic hardware resource utilization optimizations.
