DevOps & Cloud Infrastructure

Git does not have to be intimidating. Here's the mental model and the handful of commands that will cover 95% of what you need to know.

Terraform state is the source of truth for your infrastructure. Mismanage it and you get drift, corruption, and the kind of outage that makes you reconsider your career. Here's how to handle it safely.

You type a domain name. A website appears. Between those two events, a system called DNS does more work than you'd expect. Here's how it works and why it matters.

You've seen the Docker tutorial. Now here's what actually matters when you're containerizing a real application — multi-stage builds, layer caching, compose files, and the mistakes everyone makes the first time.

Most automation solves one problem and creates another: itself. Here's how to build automation that scales without becoming the next thing you have to maintain.

AWS, Azure, Vercel, DigitalOcean — understanding cloud hosting and where to deploy your code.

Automated testing and deployment, step by step. How CI/CD works and why every project needs it.

Every platform team wants to build the perfect developer experience. The ones that succeed start with the smallest thing that removes the most friction — and resist the urge to build a portal before they've built a pipeline.

Solo developer? Push to main. Two people? Branch and merge. Twenty people? You need a strategy. Here's how Git workflows evolve with team size and what actually works.

What Docker containers are, why everyone uses them, and how they solve the 'works on my machine' problem.

Your backup strategy is untested, your recovery plan is a doc nobody's read, and your RTO is 'hopefully fast.' Here's how to build disaster recovery that works when it matters.

The blinking cursor on a black screen looks intimidating. It's not. The command line is just a conversation with your computer — and it's more powerful than any GUI. Here's how to start.

Developer productivity is not lines of code or commits per week. Here's how to measure, improve, and sustain developer experience without falling into the metrics trap.

When DevOps practices hit the scaling wall, platform engineering is the answer — building internal platforms that let product teams move fast without reinventing infrastructure.

IaC solved the 'works on my server' problem. Then it created the 'nobody understands our Terraform' problem. Here's how to write infrastructure code that humans can maintain.

Before DevOps, developers wrote code and threw it over a wall to operations. It went about as well as you'd expect. Here's the problem DevOps solves and why it matters before you learn any of the tools.

A CI/CD pipeline nobody trusts is worse than no pipeline at all — it teaches the team to ignore red builds. Here's how to build pipelines that earn trust by being fast, reliable, and genuinely protective.

The cloud is not cheaper than on-premise by default — it is cheaper when managed well and ruinously expensive when ignored. Here's how to understand, predict, and control cloud spending.

The worst way to learn your automation broke is when someone asks where the report is. Here's how to build monitoring that tells you first.

DevOps is not a job title. It's a set of practices that eliminate the wall between writing code and running it. Here's what it actually means, stripped of the buzzwords.
