KubeCon + CloudNative North America 2023

The computer hardware evolution has accelerated. In just the last few years we have seen new ideas on combining heterogeneous CPU cores, multiple types of memory, a renewed focus on power saving, expectations for dynamically changing resource properties, as well as enhancements for security and confidentiality for cloud workloads and data in traditional applications and new AI model processing. This evolution forces us to revisit the resource management domain of Kubernetes. This domain is one of the most fundamental and complex areas in Kubernetes. Under the hood there are several components that Kubernetes relies on: Kubelet, Runtimes, Monitoring Agents, the OS kernel and hardware. This presentation will touch on UX changes for end users, interfaces between k8s stack components and how different pluggable algorithms, implemented via code and new policies, can help achieve evolved performance, power and resource utilization goals.
