Title: March 11, 2019: A SRE’s Journey Through Complexity

---

March 11, 2019. I wake up to a world that’s on the brink of something big—remote-first infrastructure is scaling like never before, and internal developer portals are becoming the norm. But as an engineer in this fast-moving ecosystem, my days are still filled with the relentless hum of debugging, shipping, and arguing.

Today, I find myself looking back at what we were dealing with just over a decade into our Kubernetes journey. The complexity was already there, but it felt like the tip of the iceberg compared to what’s coming now. SRE roles were proliferating, and platform engineering was formalizing. ArgoCD and Flux GitOps were maturing, but Kubernetes complexity fatigue was starting to set in for some.

I was part of a small team responsible for maintaining our internal developer portal using Backstage, an open-source framework designed to help developers manage the entire lifecycle of applications—from development to production. The idea was to create a one-stop shop where developers could get access to all their tools and documentation, but as we delved deeper into its implementation, we realized that it wasn’t just about the technology; it was about cultural shift.

One particular day, I found myself in an argument with my colleague over whether we should use Helm for managing our Kubernetes deployments. “Why not just roll out a series of YAML files?” he asked. At first, I felt like arguing back—he clearly hadn’t spent enough time in the trenches with our chaotic deployment processes. But then, I remembered all those nights spent trying to get a new service up and running only to find out that Helm templates had some subtle bug or edge case.

That’s when it hit me: Kubernetes complexity isn’t just about tools; it’s about finding the right balance between automation and simplicity. It’s about understanding where your team can benefit from an abstraction layer, like Helm, versus when a more manual approach might actually be better because you understand exactly what’s happening under the hood.

As the day went on, I reflected on how far we’d come since those early days of Kubernetes. Back then, our CI/CD pipelines were clunky and unreliable, with long build times and frequent errors. Now, they’re much more robust, but the challenges are shifting. We’re dealing with stateful applications, multi-cluster deployments, and a growing number of services that all need to work together seamlessly.

And then there was eBPF. I remember when it first started gaining attention; it felt like a beacon of hope for performance optimization. But as always, the devil is in the details. We spent countless hours figuring out how to integrate eBPF with our existing stack, only to realize that sometimes the simplest solutions are right under your nose.

Spotify’s move against Apple and Facebook’s data breaches made me think about privacy and security more than ever before. These weren’t just tech issues; they were societal ones. The implications of our work can have real-world consequences, and it’s a responsibility we don’t take lightly.

In the midst of all this, I still find myself wrestling with mundane tasks like setting up new servers or troubleshooting slow database queries. But these are the moments that define us—moments where you learn more about yourself and your team than any fancy tech talk ever could.

Today is just another day in a long journey, but it’s important to take time to reflect on how far we’ve come and what still lies ahead. As the technology landscape continues to evolve, so too must our approach to solving problems. Whether it’s with Helm or eBPF, Backstage or ArgoCD, the path forward is always about finding that perfect balance between complexity and simplicity.

This isn’t just a day in my life; this is part of the ongoing narrative of platform engineering. It’s messy, complicated, and filled with trade-offs, but it’s also incredibly rewarding. After all, every day brings new challenges and opportunities to learn and grow.
