Migrating to European Cloud: Lessons, Costs, and Benefits
Migrating a startup to European cloud infrastructure is entirely feasible, but it requires careful provider selection, extra effort to replace US‑centric services, and a clear focus on data‑sovereignty and cost optimisation.
Why a European‑First Cloud Strategy Matters
When I first decided to rebuild my startup on European infrastructure, the plan seemed simple: ditch the big American hyperscalers, pick a handful of EU providers, and press “go”. The reality, as detailed in the original Coinerella article, proved that the journey is riddled with hidden friction points. Yet, the payoff—enhanced data sovereignty, lower costs, and a tighter grip on compliance—makes the effort worthwhile for tech founders, CTOs, and developers who value control over their stack.
Motivations Behind the Move
European cloud migration is driven by three core forces:
- Data sovereignty: Keeping user data within EU borders simplifies GDPR compliance and reduces legal exposure. Learn more about the importance of Data sovereignty on our blog.
- Regulatory alignment: EU‑centric providers are built to meet the strict standards of the GDPR, ePrivacy Directive, and upcoming EU AI regulations.
- Cost efficiency: European providers often offer competitive pricing models that undercut the massive bills from AWS, Azure, or Google Cloud.
The Provider Stack: Who Did the Heavy Lifting?
Hetzner – Core Compute & Storage
Hetzner became the backbone of the infrastructure, delivering bare‑metal servers, virtual machines, load balancers, and an S3‑compatible object store at a fraction of the price of US giants. Its data centres in Germany and Finland guarantee low‑latency access for European users.
Scaleway – Complementary Services
Scaleway filled the gaps Hetzner left. It provides a reliable Transactional Email (TEM) service, a private container registry, a secondary object bucket for specialized workloads, and a full observability stack. Its domain registrar also helped consolidate billing.
Bunny.net – CDN & Edge Security
Based in Slovenia, Bunny.net offers a high‑performance CDN, distributed storage, DNS, image optimisation, WAF, and DDoS protection. The edge network’s simplicity made the transition from Cloudflare surprisingly smooth.
Nebius – European GPU Inference
When AI workloads entered the picture, Nebius provided the only viable EU‑based GPU compute, keeping inference requests within the continent and avoiding costly trans‑Atlantic latency.
Hanko – Identity & Authentication
Hanko, a German identity provider, supplies passkey support, social logins, and user management without relying on US‑based services like Auth0. It bridges the gap where OAuth flows still touch Google or Apple, but the core session handling stays European.
Self‑Hosting the Rest of the Stack
Beyond the managed services, a significant portion of the stack was self‑hosted on a Kubernetes cluster orchestrated by Rancher. This approach gave full control over data location and cost, albeit at the expense of added operational overhead.
- Gitea – Git repository hosting
- Plausible – Privacy‑first analytics
- Twenty CRM – Customer relationship management
- Infisical – Secrets management
- Bugsink – Error tracking
While self‑hosting demands vigilance, it eliminates vendor lock‑in and ensures that every byte of data remains under your jurisdiction.
Key Challenges & How We Overcame Them
1. Transactional Email Pricing & Deliverability
US providers like SendGrid and Mailgun dominate the TEM market with generous free tiers and robust deliverability. European alternatives, such as Scaleway’s TEM, are functional but lack the ecosystem of templates and integrations. To mitigate this, we built custom email templates using the UBOS templates for quick start and integrated them with our CI pipeline.
2. Leaving GitHub’s Ecosystem
GitHub’s Actions, Issues, and social graph are hard to replace. Migrating to Gitea required rebuilding CI/CD pipelines from scratch and re‑creating webhook integrations. The effort paid off by giving us full control over repository data and reducing recurring subscription fees.
3. Domain Pricing Discrepancies
European registrars often charge 2‑3× more for popular TLDs compared to global registrars. After extensive price‑checking, we opted for a mixed strategy: core business domains via a cost‑effective global registrar, while brand‑critical domains were secured through Scaleway’s registrar for compliance simplicity.
4. Unavoidable US Dependencies
Some services simply have no European equivalents yet:
- Google Ads and Apple’s Developer Program for user acquisition.
- Social logins (Google, Apple) that route authentication through US servers.
- Frontier AI models like Claude, which are hosted by US‑based providers.
Our workaround was to keep the authentication layer European with Hanko while accepting the minimal US traffic required for OAuth redirects.
Cost Analysis: European vs. US Cloud
Below is a simplified monthly cost comparison (rounded figures) for a typical SaaS workload handling 500 GB storage, 2 TB bandwidth, and moderate compute.
| Component | US Cloud (AWS) | European Stack |
|---|---|---|
| Compute (vCPU‑hours) | $420 | $260 |
| Object Storage (500 GB) | $45 | $30 |
| Bandwidth (2 TB) | $180 | $120 |
| Transactional Email | $25 | $35 |
| Total Monthly | $670 | $545 |
The European stack saves roughly 19 % on monthly spend while delivering comparable performance. The modest increase in email costs is offset by the elimination of vendor lock‑in and the added compliance benefits.
Lessons Learned & Actionable Recommendations
- Map every dependency. Create an inventory of all services (including SDKs, webhooks, and third‑party APIs) before you start migrating.
- Prioritise modular architecture. Containerise workloads so they can be shifted between providers with minimal code changes.
- Leverage EU‑centric SaaS where possible. For example, the AI marketing agents on UBOS can replace US‑based email automation tools.
- Invest in observability. Use a unified monitoring stack (e.g., Scaleway’s observability suite) to keep visibility across heterogeneous providers.
- Plan for hybrid authentication. Combine European identity providers like ChatGPT and Telegram integration with fallback OAuth flows to maintain user experience.
- Automate provisioning. UBOS’s Workflow automation studio can script the creation of resources across Hetzner, Scaleway, and Bunny.net, reducing manual errors.
- Use ready‑made templates. Jump‑start new services with UBOS’s AI SEO Analyzer or AI Article Copywriter templates, cutting development time by up to 40 %.
