Multi-tenancy often means choosing between efficiency and isolation.
Private Nodes make it possible to get both, clean separation for tenants without managing dozens of clusters.

In this post, @stmcallister.bsky.social breaks down why it matters:

YouTube video by CNCF [Cloud Native Computing Foundation] Keynote: Pushing the Limits: Scaling ArgoCD’s Repo-Server To Handle 30... Aditya Sharma & Isha Gusai

At #KubeConIndia, the Expedia platform team shared how they tested Argo CD at scale, 30,000+ apps across 100+ clusters.
They used vCluster to simulate the environment and run structured tests across Helm, autoscaling, memory, and gRPC behavior.

Scaling Kubernetes Without the Pain of etcd Sharding OpenAI’s outage revealed what happens when etcd breaks at scale. This post explains why sharding isn’t enough, and how vCluster offloads API load with virtual control planes. Benchmark included.

Too many CRDs. Too many controllers.
One shared etcd.

We ran a benchmark to see what happens under load:
• Host cluster: etcd latency hit 650ms
• vCluster: near-zero - fully isolated

@saiyampathak.com will be speaking at #KubeConIndia alongside Arnab Chatterjee.

Their keynote dives into how a tenant failure brought down a multi-tenant Kubernetes cluster, and what changed to make the platform more resilient.

Running AI/ML workloads on Kubernetes with bare-metal GPUs?

Multiple clusters drive up cost, and namespace isolation isn’t enough for security or control plane separation.
