We’ve all seen this movie:
You build a “simple” Flask or Django app. You dockerize it. You deploy it on Kubernetes. Then you look at your node metrics and wonder why your app is eating memory like a Chrome tab farm.
And here comes the uncomfortable truth: Go apps don’t do this.
Concurrency: Built-In vs. Bolted-On
Python still has the Global Interpreter Lock. AsyncIO, threads, gevent: all clever duct tape.
Go’s goroutines? Native. Dirt cheap. A Go service can juggle tens of thousands of requests without you even thinking about it. Meanwhile, your Python service is scaling horizontally like it’s on cloud provider commission.
Deployment: One Binary vs. Frankenstack
Running Python in production is like dragging a circus into your Pod spec:
Gunicorn or Uvicorn
WSGI or ASGI adapters
Reverse proxy like Nginx
Virtualenvs just to keep packages sane
Each one is another container, another moving part, another thing to patch.
Go? One binary. One container. One Deployment. Done.
Memory: Lean Pods vs. Hungry Pods
Here’s what happens under load:
Go Pod: ~30–50 MB steady, serving requests.
Python Pod: 200–300 MB per worker.
Kubernetes doesn’t care about your excuses. Requests and limits balloon, the autoscaler spins up more nodes, and your cloud bill burns.
The funny part? Your app isn’t even complex. The runtime is.
Magic vs. Predictability
Python is “dynamic.” Translation: you find out about your bugs at runtime, usually while your Pod is CrashLooping.
Go is boring. Strict. Unforgiving at compile time. But once that binary ships, it just runs. Kubernetes likes boring. Operators like boring. Your SRE team loves boring.
Ecosystem: AI Crown vs. Web Pretender
Yes, Python owns the AI/ML world. If you’re training models, you’re not reaching for Go.
But for web apps? The Python ecosystem is bloated and patchwork. Go’s standard library gives you a production-ready HTTP server out of the box. No circus, no adapters, no excuses.
Python is fantastic for notebooks, scripts, and ML. But for web apps in Kubernetes? It’s a bloated liability.
Go apps scale cleaner, run cheaper, and keep clusters saner.
Stop pretending Python web apps are fine in production. They’re not. They’re expensive. They’re messy. And they’re only still around because developers are in denial.
Sometimes the boring choice is the right one. In Kubernetes, boring wins.
