Show HN: We moved from AWS to Hetzner, saved 90%, kept ISO 27001 with Ansible

Earlier this year I led our migration off AWS to European cloud (Hetzner + OVHcloud), driven by cost (we cut 90%) and data sovereignty (GDPR + CLOUD Act concerns).

We rebuilt key AWS features ourselves using Terraform for VPS provisioning, and Ansible for everything from hardening (auditd, ufw, SSH policies) to rolling deployments (with Cloudflare integration). Our Prometheus + Alertmanager + Blackbox setup monitors infra, apps, and SSL expiry, with ISO 27001-aligned alerts. Loki + Grafana
