Migrated a 3-service Django application from AWS to Hetzner, reducing monthly infrastructure costs by 74% with zero downtime and improved performance.
A SaaS startup was paying $340/month for AWS infrastructure that was 80% idle. The application — a Django API, a PostgreSQL database, and a Celery worker — was running on EC2 instances sized for traffic projections that never materialised.
We migrated the full stack to a Hetzner CX32 (€14.39/month) with Docker Compose orchestration, Cloudflare as the CDN and DDoS layer, and daily encrypted backups to Hetzner's object storage. Zero-downtime migration using DNS-level traffic switching.
74% cost reduction — from $340 to $89/month (Hetzner + Cloudflare + backups). P95 response time improved by 30% due to lower network latency. System has run without incident for 8 months.
