• Zero-Day Runtime Isolation for Containers: Rethinking Dependency Trust

  Francesco Vitullo

  This article asks what a container can block on its own when a dependency turns malicious, and tests nono, a capability-based sandbox that limits file and network access at runtime.

• Scaling Kubernetes Deployments to multiple Regions: A GitOps Reference Architecture

  Vtulasinadh

  This article lays out a GitOps reference architecture for running one app across 25 regions, where every region reconciles itself with Argo CD and a rollback is a git revert scoped to that region alone.

• Leaked Kubernetes Secrets: Impact Assessment and Mitigation Strategies

  Dwayne McDaniel

  This article explains what an attacker can really do with leaked Kubernetes credentials, from kubeconfigs to service account tokens, and how to check the blast radius and shut it down.

• Distributed Consensus at Scale: Running Zookeeper on GKE with Local SSD (Z4D)

  Anuj Ashok Potdar

  This article explains how running ZooKeeper on Google Cloud Z4D nodes with local SSDs removes the disk latency that slows consensus writes, plus the GKE anti-affinity, volume binding and JVM tuning it needs.
