There’s a reactive way to manage infrastructure and there’s a proactive way. The reactive way is: traffic increases, you notice the service is suffering, you add resources. The proactive way is: you understand your system well enough that it handles demand changes automatically, without you needing to be in the loop.

I prefer the lazy way.

First, a thought about what this is and what it isn’t: this is about website metrics management. Not the only way, but one way for a high-level overview.

I’m focused on sharing concepts about website monitoring and one possible way to manage this in Kubernetes. You can reach the same goal with just Docker and crontab — but I’m using some other tools in Kubernetes because I’m evaluating them for other purposes.
