From ECS to Kubernetes: A Real Migration Story

Migrating from ECS to Kubernetes sounds straightforward — until you hit spot capacity failures, firewall rules silently dropping traffic, and memory metrics that lie to your autoscaler.

Radosław Miernik, Head of Engineering at aleno, walks through a real production migration: what broke, what they missed, and the fixes that made it work.

In this interview:

Running Flux and Argo CD together — Flux for the infra team, Argo CD's UI for developers who don't want to touch YAML
How the wrong memory metric caused OOM errors, and why switching to jemalloc cut memory usage by 20%
Splitting WebSocket and API containers into separate deployments with independent autoscaling

Four months of migration, over 100 configuration changes in the first month, and a concrete breakdown of what platform work looks like when you can't afford downtime.
