Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
Provision real cloud resources with Terraform — a VPC, an S3 bucket, and an EC2 instance — using the standard init/plan/apply workflow.
GitOps in plain words — what it actually is, the workflow it enables, and a hands-on demo using Argo CD on a local Kubernetes cluster.
Install Ansible, write your first playbook, and configure a remote server (nginx + a deploy user) without touching it manually. The basics that scale up.
A 2 AM incident, the autovacuum settings that caused it, and the parameter changes that prevented the next one. The discipline that took our biggest Postgres host from periodic stalls to steady.
We launched Backstage in October. Six months in, 80% of services are catalogued, on-boarding takes a third of the time, and we mostly know what owns what.
We ran Pulumi in TypeScript and Terraform in HCL side by side across 60+ services. Each won different categories of work. Here's the breakdown.
How we shipped three schema migrations with zero customer impact. Expand-then-contract, dual-writes, and the rollback plan we never had to use — but tested anyway.
We were drowning in 200 alerts a week. Most got ignored. After a quarter of triage and rework, we're at about 15 — and on-call actually responds to them.
Practical patterns for Terraform modules at scale: versioning, composition, testing, and avoiding the monolith trap.
A real-world Terraform module version pinning guide for platform teams that want safer upgrades, clearer ownership, and fewer broken pipelines after shared module releases.
A practical Terraform state isolation guide built from a real environment-mixing incident, with patterns for safer backends, clearer ownership, and lower blast radius.
This infrastructure documentation as code guide shows how a platform team moved runbooks, ownership maps, and architecture decisions into versioned workflows that people actually trusted.
