Technical deep-dives on GCP, Kubernetes security, CI/CD pipelines, GitOps workflows, and cloud-native infrastructure. Every article is based on real production engagements — no fluff, just actionable engineering.
Over-provisioning burns cloud budget. Under-provisioning causes production incidents. Kubernetes has multiple built-in and add-on autoscaling mechanisms, and picking the right combination for your workload is the difference between a stable, cost-efficient cluster and a constant firefight. This guide covers HPA, VPA, KEDA, and the cluster autoscaler with practical examples.
PodSecurityPolicy was removed in Kubernetes 1.25, but many teams still run without a replacement. Pod Security Admission is built into the API server and requires no extra controllers. Here is a practical step-by-step migration plan covering audit, warn, and enforce modes, plus how to handle privileged workloads.
Losing etcd means losing every workload, secret, and configuration in your Kubernetes cluster. This guide covers Backup for GKE, snapshot-based strategies, automated scheduling, disaster recovery procedures, and how to test your restore plan before you need it.
CI/CD pipelines are now the primary attack surface for modern infrastructure teams. Here is a practical approach to securing pipeline credentials, integrating SAST and SCA scanning, signing build artifacts, and enforcing automated security gates before production deployment.
GKE clusters often exceed budget due to overallocated workloads and inefficient autoscaling. This guide covers right-sizing, spot VMs, committed use discounts, and cost monitoring to cut your Kubernetes bill.
Every CI/CD pipeline is a supply chain, and every step between source code and production is an attack surface. This guide applies the SLSA framework to harden build pipelines with provenance generation, hermetic builds, and verifiable attestations so your team can prove what ran in production and how it got there.
Most production clusters still run with over-privileged service accounts. Here is a repeatable approach to auditing RBAC, designing scoped roles, and automating enforcement so your permissions stop drifting.
Every GKE cluster that accesses GCP APIs faces the same question: how does a pod prove its identity without embedding a long-lived service account key? Workload Identity replaces static keys with federated IAM, giving pods short-lived, automatically rotated credentials scoped to a specific namespace and service account.
A production Kubernetes outage is not the time to start writing runbooks. Platform teams need pre-built detection signals, triage commands, forensic collection procedures, and communication templates ready before the first alert fires.
Kubernetes Network Policies are the built-in firewall for pod-to-pod communication. This guide covers default-deny rules, namespace isolation, policy testing, and a practical checklist for enforcing zero-trust networking in production clusters.
