Node Resource Management: The Big Picture - Sascha Grunert & Swati Sehgal, Red Hat; Alexander Kanevskiy, Intel; Evan Lezar, NVIDIA; David Porter, Google
Resource management is a fundamental area in Kubernetes that focuses on how to properly reserve, allocate, and isolate finite resources on nodes such as CPU, memory, disk, network, accelerators, etc. Resource Management is a hot topic, with multiple proposals raised recently on how to improve things both in Kubernetes and container runtimes: Dynamic Resource Allocation, QoS class resources, improvements to CPU Management, to container lifecycle management and statistics, support in CRI-enabled container runtimes for advanced low-level runtimes such as Kata containers, Firecracker, gVisor, and Confidential Containers and many more. In this presentation, speakers will present the “big picture” for these proposals, how they are interconnected, how they are different, which problems they are targeting to solve, and what they mean for Kubernetes users. This presentation will be helpful for cluster administrators and users to understand the future direction in their resource management area and give a framework for them to provide feedback that can help shape these future efforts. We will also describe opportunities for folks who are more interested to get involved with the open source SIG-Node and runtime communities to drive these efforts forward.
