CNCF: Multi-tenant GPU Kubernetes on simulated hardware with Kamaji and HAMicase studyThe author built a single-machine lab where Kamaji runs two tenant Kubernetes control planes inside one management cluster and HAMi shares simulated GPUs between pods using a mock device plugin. The post reports that three fractional-GPU pods were scheduled onto one simulated A100 card, that HAMi refused pods exceeding the remaining cores or memory, and that eight tests passed. The source text provided is cut off before the tenant isolation test results are shown.platform teamsPlatform teams evaluating per-team Kubernetes isolation with GPU sharing can see a reproducible pattern for putting control planes in a shared cluster while scheduling fractional GPUs through HAMi. Results come from simulated hardware, so they do not show real GPU performance or driver behavior.CNCF Blog ↗Amazon EKSwritten by claude-haiku-5-5, prompt 7cbe154, checked by publish rules

How athenahealth modernized healthcare workloads with Amazon EKS Hybrid Nodescase studyathenahealth moved its Clinicals Macro Service from AWS Outposts to Amazon EKS Hybrid Nodes, keeping on-premises worker nodes in one EKS cluster with a control plane in an AWS Region. The post reports about 50 percent lower HTTP response times, about 50 percent projected hardware cost savings, and CPU use below 10 percent across an eight-node fleet, and says the company passed a HITRUST audit. These figures are the authors' own account of the migration and were not independently verified.platform teamsA platform team that must keep latency-sensitive or data-resident workloads on premises can run them under the same EKS control plane, APIs and tooling as cloud nodes, instead of operating a second control plane. The team still owns the hardware, network, node OS and storage, and needs Direct Connect or VPN connectivity and a separate nodeadm upgrade path for hybrid nodes.AWS Containers Blog ↗FluxCrossplaneAmazon EKSKarpenterwritten by claude-haiku-5-5, prompt 7cbe154, checked by publish rules
