14 min read · automate database schema changes through CI/CD and GitOps
When app deploys and schema changes run on different tracks, production breaks fast. This guide turns migrations into first-class delivery artifacts with Flyway or Liquibase, forward-safe expand-contract rollouts, and GitOps-aware execution order.
10 min read · reduce multi-cloud spend with measurable engineering guardrails
Surprise cloud bills usually trace to visibility gaps, idle capacity, and data movement—not a single misconfigured instance. This playbook maps cost levers across AWS, GCP, and Azure, with tagging, commitments, guardrails, and a weekly review loop teams can run without freezing delivery.
14 min read · Kubernetes security hardening for production clusters
Default clusters are easy targets for RBAC sprawl, open APIs, and plaintext etcd. This guide walks through control plane flags, Pod Security Standards, default-deny networking, node sysctl hardening, and Vault-style secrets—with a phased rollout plan.
12 min read · GitOps delivery with Argo CD or Flux on Kubernetes
Git as the contract of record stops silent drift across clusters. Compare Argo CD and Flux patterns—from install snippets to policy hooks—and adopt guardrails for secrets, observability, and audit-ready rollouts.
11 min read · secrets, credentials, and certificates in DevOps CI/CD pipelines
CI/CD needs secrets, yet sprawl and logs multiply risk. This guide covers a centralized pattern, Vault with GitLab, Kubernetes CSI mounts, and guardrails for rotation, access, and audit.
9 min read · Infrastructure as Code testing with Terraform, Test Kitchen, and InSpec
Faulty IaC still causes outages and cost spikes. This article lays out a layered test strategy, a Kitchen-Terraform plus InSpec walkthrough for an AWS S3 module, and practices that keep infra tests honest in CI.
10 min read · resilience engineering and controlled failure testing in DevOps
Most outages are not caused by unknown bugs but by untested failure behavior. This guide explains how to run hypothesis-driven chaos experiments safely, measure impact, and turn findings into repeatable resilience improvements.
7 min read · delivery speed and CI/CD bottleneck diagnosis
A practical framework to identify delivery constraints and improve lead time without overhauling your stack.
