Case Studies on Raus.cloud — Resilient, Sovereign Infrastructure

The €8 to €800 Scaling Roadmap

Mon, 05 Jan 2026 00:00:00 +0000

European B2B SaaS startups waste between 10% and 90% of their runway on infrastructure they don’t need. They scale complexity instead of value delivery, burning cash on solutions designed for companies 100x their size. (We covered the macro trend of cloud repatriation in a previous article.)

After analyzing patterns across 50+ infrastructure assessments, I’ve found that matching infrastructure spending to actual revenue—not imaginary scale—can reduce costs by 60-70% while improving performance.

Cloud Repatriation in 2025: What the Numbers Actually Say

TL;DR for busy readers:

70% of enterprises plan to repatriate workloads by 2026 — you’re not crazy for considering it

42% of IT pros already moved from cloud back to dedicated servers last year

Typical savings: 30-50% on infrastructure costs

Startups have more freedom than enterprises — no vendor politics or procurement cycles

Our test: €7.59/month VPS vs €10,560/month AWS Lambda for same workload (1,400x difference)

Spending €5k-15k/month on cloud? We can help you evaluate options

What if the infrastructure you’re paying for could cost you half as much—with better control?

The Lean DevOps Stack: From Git Push to Production in 2 Minutes

The Promise: Production-Grade DevOps Without the DevOps Team

In Part 1 of this series, we proved that a single €7.59/month VPS outperforms Docker Swarm by 37%. But performance is only half the story.

The other half: How do you actually deploy code to that VPS without spending your evenings debugging YAML?

This article documents our setup: Coolify + Docker Compose + Terraform. Three tools that give us:

2-3 minute deploys triggered by git push
Preview environments for every PR (39 seconds to spin up)
Auto-HTTPS via Let’s Encrypt
Infrastructure-as-code for disaster recovery
Zero DevOps hires required

Total monthly cost: €7.59 for the application server, plus €3.79 for the Coolify control plane.

We Spent €11/month Testing Docker Swarm So You Don't Have To

Executive Summary: Load Test Results

We tested four architectures with identical code, identical load patterns (up-to 1200 concurrent users, 4.5 minutes), and identical Hetzner infrastructure. Here’s what we learned:

Test	Architecture	vCPU	Monthly Cost	RPS	Cost per 100 RPS	P95 Latency	Errors	Result
1	Single CAX11	2	€3.79	228	€1.66	5,303ms	0.80%	❌ Failed
2	2×CAX11 Swarm (balanced)	4	€7.58	354	€2.14	3,524ms	0.00%	✅ Passed
3	Single CAX21	4	€7.59	484	€1.57	2,462ms	0.00%	🏆 Winner
4	CAX21+CAX11 Swarm (asymmetric)	6	€11.38	343	€3.32	3,557ms	0.00%	❌ Worse than Test 2

Single-server architecture: Everything runs in Docker Compose.
