Taming the Chaos in a New DevOps World

---

September 27, 2010 was just another day in the life of a young engineer. But as I sat down to write this, the DevOps movement was still finding its footing and the chaos engineering practices that would become commonplace were just whispers in the wind.

I remember when Chef was getting its foot in the door against Puppet, a battle that seemed to rage on forever. The tools we used felt like clunky instruments of our trade—more akin to hammers than the fine-tuned screwdrivers I’d grown up with. Yet, as I dove into these new systems, I found myself intrigued by their potential.

I had just joined a startup that was all about “moving fast and breaking things.” The phrase itself seemed almost poetic in its defiance of traditional IT practices. We were building a platform for startups, pushing the envelope on what could be built quickly and cheaply. But with every feature came an unwelcome side effect: complexity.

One day, I was tasked with debugging a mysterious issue that had cropped up during our latest deployment. Our application was acting erratically across multiple environments—stability was something we aspired to but seemed to elude us at every turn. We were still using manual deployments and had no formal change management process in place. Every time we pushed code, it felt like a crapshoot.

As I started digging into the logs and trying to figure out what was going wrong, my colleague walked over with a cup of coffee. “So,” he said, “have you checked the new Chef run? Maybe something is off there.”

I nodded, feeling a bit sheepish. Here we were, building our platform on top of these configuration management tools that felt like they were still in beta. But every time I tried to implement best practices, someone would argue, “Well, but it works right now,” or “Let’s just deploy and fix it later.”

The thought of embracing chaos engineering was daunting. The idea of deliberately breaking things to improve resilience seemed counterintuitive. Yet, as the weeks passed, our system kept failing in unpredictable ways. I started to see a pattern—certain parts of our infrastructure would fail at the worst possible times.

One night, I sat down and began to write some basic chaos scripts. Small, innocuous things that would randomly stop services or roll back configurations. It was like playing god with my own application, but it felt necessary. We were in a world where every day brought new challenges and opportunities for disaster.

I shared these scripts with the team and watched as they grappled with the idea of intentionally destabilizing their own systems. But as we ran tests, the results were clear: our infrastructure was too brittle. Small changes or even non-critical failures could cascade into major outages.

Over time, we started to see improvements. Our system became more resilient, and our deployments became less risky. The scripts evolved from simple chaos experiments to a robust framework that allowed us to test and improve our systems regularly.

Looking back on it now, those early days of DevOps were a crucible. We learned the hard way that moving fast didn’t mean being reckless; it meant having the tools and processes in place to ensure stability even as we innovated. The emergence of Chef and Puppet wasn’t just about configuration management—it was a call to arms for a new approach to software development and deployment.

As I close this entry, I can’t help but feel that much has changed since 2010, yet so little has. The tools have evolved, the buzzwords have come and gone, but the core principles of DevOps remain: embrace automation, continuous integration, and an openness to failure as a means of growth.

That day in September was just one chapter in the ongoing narrative of building resilient systems, but it taught me that sometimes, you need to break things to make them better.
