Title: Reflections on February 2023: When the Serverless World Crashed into My Life

---

February 13th, 2023. Another day of ops and platform engineering, but this one felt different. The tech world had been buzzing about AI and LLMs (Large Language Models) since ChatGPT blew up in January. Platform engineering was finally getting the recognition it deserved, and FinOps were turning into a real discipline to manage cloud costs.

I’d spent most of my day debugging a particularly stubborn issue with one of our services that relied heavily on serverless infrastructure. This wasn’t just any service; it handled sensitive user data and needed to be rock-solid. The root cause was tricky because the serverless architecture made tracing dependencies and errors difficult.

The environment was a mix of AWS Lambda, Kinesis streams, and DynamoDB—basically the dream setup for ops nightmares. Each layer had its own quirks and latency issues that compounded when something went south. I spent hours piecing together logs from CloudWatch and trying to simulate the issue locally only to realize that the problem was somewhere upstream.

This reminded me of a classic saying: “Debugging is twice as hard as writing the code in the first place.” And it’s not just about fixing bugs; it’s understanding why they happen. In this case, I had to dive deep into how the data flow worked, what triggers were firing, and how different services interacted.

The problem turned out to be a caching issue with DynamoDB. A recent update to our service had inadvertently caused some of the cache entries to expire prematurely, leading to inconsistent reads. Once I identified it, resolving it was straightforward, but getting everyone on board to fix the root cause took longer than expected. It’s always easier to say “let’s just do a quick hack” than to address the underlying issues properly.

On top of that, we were dealing with the influx of developers trying out new tools and frameworks. WebAssembly on the server side was still in its infancy but showing promise for performance optimizations. I found myself arguing with a team member about whether it was worth exploring this path given our current architecture and constraints. My stance was always to weigh potential benefits against added complexity and risk, but sometimes you just have to take that leap.

Speaking of complexity, FinOps were becoming more prominent in our organization. With cloud costs skyrocketing, we needed to get a better handle on what was going where and why. I had been tasked with setting up a cost monitoring dashboard using Grafana and AWS Cost Explorer. It wasn’t glamorous work, but it felt important. Being able to trace back specific charges directly to code changes or new features could help us make more informed decisions about resource allocation.

As the month progressed, I found myself thinking about all these issues in the context of the broader tech landscape. The AI and LLM hype seemed to overshadow everything else. Seeing posts like “Bing: ‘I will not harm you unless you harm me first’” made me wonder how these technologies would evolve and impact our work. Meanwhile, articles about DIY repairable phones from Nokia were a stark reminder that the tech industry still had much to learn about sustainability.

Developers’ easter eggs in flight paths of aircraft deliveries or even my daughter’s school taking over my personal Microsoft account underscored the human element in technology. These small, whimsical moments highlighted how deeply intertwined our lives are with digital tools and services now.

And finally, discussions around Firefox as an awesome browser right now made me reflect on the choices we make daily as consumers and professionals. The world of web development was changing rapidly, and staying ahead meant constantly reassessing not just what technologies to use but also how they fit into our broader goals.

As February drew to a close, I felt both frustrated and invigorated. Frustrated because debugging issues like the one with DynamoDB could be so frustratingly complex; invigorated by the prospect of exploring new tools and frameworks that might make our lives easier in the future.

In short, it was another month filled with challenges, learning, and growth. The tech world continued to evolve at a breakneck pace, and as always, I found myself both leading and following these changes.
