Title: December 2021: When DevOps Met the Stealth Bomber

---

December 27, 2021. Another year wrapped up in the tech world. The past months saw platform engineering solidify its place as the new norm for organizations looking to streamline their development and operations processes. We were deep into SRE roles with more teams than ever embracing GitOps practices like ArgoCD and Flux. Kubernetes complexity was starting to feel real, so I found myself buried in some heavy discussions about whether we should standardize on a single tool or if the variety of options was actually making our lives easier.

On my personal front, I’ve been wrestling with something that’s both humbling and frustrating: finding the right balance between being an active participant in technical conversations and not overstepping into management responsibilities. Sometimes it feels like we’re all lying about how much work we do on Ask HN, but then I realize I’m just too busy to document everything.

I started the month with a minor victory: debugging an issue that had been plaguing our internal developer portal for weeks. The problem was a tricky one—a race condition in some asynchronous processes that only occurred under specific load conditions during certain times of day. It took a few days of logging and tracing, but we finally got to the bottom of it using Jaeger and Prometheus together.

But then came the AWS outage on December 15th. It was like a reminder that no matter how much we scale our infrastructure, the cloud providers can still bring us down. I spent a tense afternoon working through disaster recovery plans with my team, making sure we had all the bases covered. That night, I lay awake thinking about the resilience of our systems and wondering if we should be doing more proactive monitoring and failover testing.

In between these moments, I found myself reflecting on some of the bigger tech stories that caught my eye. The stealth bomber in Google Maps was a cool reminder that sometimes the most advanced technology is right there under our noses, waiting to be discovered. And then there’s the Log4j RCE incident—scary stuff that made me double-check all our dependencies.

Meanwhile, at work, we were starting to see more teams adopt eBPF for performance tuning and monitoring. I’m cautiously optimistic about it; it seems like a powerful tool in the right hands. But as with anything new, there’s still a learning curve and some potential pitfalls.

One of my colleagues shared an interesting article: “I started a paper website business.” It made me smile because it reminded me that sometimes the simplest projects can turn into big success stories. I often feel like we’re so focused on building complex systems that we forget about the elegance in simplicity.

And then, just as I was wrapping up my day with some self-deprecating thoughts, I got a call from Pixel—of all things! I couldn’t believe someone had blocked their emergency calls because of privacy settings. It’s moments like these that make you realize how far technology has come but also how much we still have to learn about using it responsibly.

As the year comes to a close, I find myself reflecting on the journey so far. The tech world is ever-changing, and it can feel overwhelming at times. But amidst all the complexity and constant learning, there’s something comforting in knowing that every challenge we face brings us closer to building better systems for our users.

Happy holidays, everyone. Let’s hope 2022 brings even more exciting opportunities and fewer outages.
