Title: August 5, 2013 - A Day in the Life of a DevOps Nerd

---

August 5, 2013 was another one of those days that felt like it spanned an entire decade. I woke up at my desk in the office, nursing a cold brew and reviewing yet another ticket from our happy-hour chatops channel. The team was buzzing; they were preparing for a major release on our e-commerce platform, and we had some critical bugs to iron out.

I started by checking our Jenkins build server, which was humming along nicely with over 200 concurrent builds. Our CI/CD pipeline was a marvel of complexity, but it worked most of the time. I glanced at the Docker logs; they still seemed cryptic even after all these months. I quickly realized that one of our containers had failed to restart properly and was causing issues with our database service.

I pulled up etcd’s UI to check on the cluster health. Everything looked good, but the real test would come once we brought everything down for a redeploy. I switched over to IRC and joined the ops channel where everyone was discussing potential risks and mitigation strategies. We were using CoreOS and fleet at this point, which was still new ground for us.

“Hey Brandon,” one of my teammates chimed in from another screen, “you think we should go with Marathon or stick with Kubernetes?” The conversation quickly devolved into a debate about the merits of Mesos over Docker Swarm. I sat there, flipping through Hacker News on the side and reading about Lavabit’s shutdown and the Hyperloop hype.

I took my laptop to the kitchenette for some coffee. As I sipped it, I found myself thinking about security. The Lavabit story had really hit home; we were storing sensitive user data, and any breach could be catastrophic. We needed a better backup strategy, but budget constraints made that challenging. I jotted down a few notes to discuss with the team later.

Back at my desk, I dove into the code for our e-commerce service, which was written in Node.js and deployed using Docker containers. The 12-factor app principles were still very much on my mind. We had moved away from traditional monoliths towards microservices, but the complexity of managing all those services had grown exponentially.

At lunch time, we had a quick stand-up with our product manager to discuss user feedback and upcoming features. She brought up an interesting point about adding real-time updates using WebSockets, which would require some significant changes to our infrastructure. We talked through potential solutions, including leveraging Kubernetes for load balancing and etcd for state management.

As I walked back to my desk after lunch, I stopped by the team’s Slack channel and saw a message from the SRE team about the upcoming Google reorg. “SRE is now a separate department,” it read. That was news to me; it seemed like every day there was some new change in how things were organized at Google.

I decided to take a break and walk over to our local coffee shop down the street. On the way, I saw a group of developers discussing something about VR or AR—Oculus maybe? I couldn’t resist joining their conversation for a bit. John Carmack joining as CTO was still quite a buzz. I imagined him coding up some cool new features with his team.

Returning to my desk, I sat down and started coding a fix for the failing container issue. It wasn’t long before the rest of the team joined me in the kitchenette for more coffee and discussion about our upcoming release plan. We decided to go with a staged rollout approach using Marathon for now, hoping it would help us catch any issues early.

As the day wore on, I found myself thinking about how much tech had changed just over the past year. Docker was still young, Kubernetes hadn’t yet been announced, and even the SRE book was still in development at Google. But we were learning, growing, and pushing the boundaries of what was possible with these new technologies.

The day ended with a successful redeploy and a sense of accomplishment, but also an awareness that there was so much more to do. As I packed up my laptop, I couldn’t help but feel grateful for being part of such an exciting time in tech. It was clear that the future was going to be full of challenges and opportunities—just like this day had been.
