Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
Practical patterns for Terraform modules at scale: versioning, composition, testing, and avoiding the monolith trap.
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 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 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 Terraform state isolation guide built from a real environment-mixing incident, with patterns for safer backends, clearer ownership, and lower blast radius.
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 hands-on guide to AWS cost allocation tags for shared environments, built from a real platform-team problem: everyone used the cluster, but nobody trusted the bill.
We cut our AWS bill by 38% in a quarter. The specific changes that moved the bill, ranked by impact, with what we'd do first.
We run mostly on AWS but use GCP for specific workloads. The honest cost-benefit analysis of multi-cloud, plus the patterns that make it not awful.
A different angle on DR: the planning process — RTO/RPO conversations, dependency mapping, and what we learned about prioritizing what to recover.
Embed cost ownership in engineering: tags, budgets, and showback.
We cut our largest playbook's runtime from 14 minutes to 4 minutes. The specific changes that mattered, plus the ones that didn't.
