Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
A real cost audit uncovered idle load balancers, oversized RDS instances, and forgotten snapshots. Here's what we found and how we fixed each one.
A real-world model fallback guide for customer-facing AI systems, covering how one team preserved response quality and support SLAs during a partial provider degradation.
A hands-on RDS restore drill guide for small cloud teams that thought backups were covered until a timed restore test exposed missing steps, DNS confusion, and stale credentials.
A practical systemd drop-in guide built from a real operations problem: vendor unit files kept changing, but the team still needed consistent restart, environment, and logging behavior.
A practical embedding model upgrade guide for RAG systems, built from a real support-search migration that initially reduced answer quality instead of improving it.
A real-world multi-cluster traffic routing guide for SaaS teams that have outgrown a single Kubernetes cluster and need safer rollout control without a service-mesh science project.
A practical systemd reliability guide for Linux services, built around repeated restart-loop incidents and the unit-file patterns that finally made those services boring.
A practical disaster recovery runbook guide for small cloud teams that need realistic failover steps, clear ownership, and repeatable rehearsals instead of shelfware documents.
A real story of removing console-only changes, adding drift detection, and getting Terraform back in charge.
How a small team moved from single-region risk to a simple active/passive multi-region setup without doubling complexity.
