Getting workloads onto Kubernetes is the easy part. The migrations that fail usually fail on operational readiness, not on the cluster itself.
This is where I write about the parts of platform engineering that don’t make it into vendor docs: running Kubernetes — including on bare metal — in production, CI/CD pipeline design decisions and their tradeoffs, Vault and secrets management patterns, and the operational realities of keeping infrastructure reliable and cost-aware at scale. Expect technical detail over hot takes.
