Hetzner Migration Slashes Bill, Zero Downtime

This is a strong example of when cloud convenience stops paying for itself. Once a workload is steady-state and operationally disciplined, dedicated hardware can deliver a much better price-performance ratio. The real value is the migration playbook: MySQL replication, DNS TTL reduction, and reverse-proxy fallback turned a risky move into a controlled cutover. The article is practical rather than theoretical, with useful details like `mydumper`/`myloader`, webhook cleanup, and rollback-safe scripting. The `SUPER` privilege gotcha is the kind of production issue teams only learn the hard way; it is a good reminder to audit permissions before treating a replica as read-only. This is less “move to Hetzner” and more “rethink infra economics once autoscaling and managed platform features are no longer essential.”
