DigitalOcean to Hetzner Fleet Migration

The platform was paying too much for hosting and had hit a performance ceiling. I spent two months planning the move on my own: capacity sizing, topology, cutover sequencing, rollback design, and data-integrity checks, all provisioned with Ansible. The cutover crossed the app, database, Redis, load-balancer, and monitoring tiers in one pass. It saved roughly $5,000 a month, ran 5 to 20 times faster, and held 99.97% uptime.
