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.
