Monitoring & intervention

Is your cloud infrastructure holding you back or driving you forward?

Unstable infrastructure

Recurring outages, services going down without warning, unhappy customers.

Revenue loss with each outage, damaged reputation, stressed teams.

Unpredictable and opaque costs

Cloud bills doubling without explanation. Oversized resources. Exploding licenses.

Recurring budget overruns, inability to plan.

Data outside Switzerland

Your data is with Microsoft, Google or Amazon - subject to the US Patriot Act / CLOUD Act.

Legal risk, non-compliance with DPA/GDPR, loss of client trust.

Technical complexity

You're not a cloud expert. Management takes time you don't have.

Wasted time, frustrated team, slowed innovation.

Limited scalability

Unable to absorb load spikes. Growth blocked by infrastructure.

Lost opportunities, stagnation.

Vendor lock-in

Locked with a US hyperscaler or rigid host. Proprietary formats, prohibitive exit costs.

Overpaying, no negotiating leverage, captive data.

These problems are not inevitable. They share a common cause: the lack of architecture designed for YOU. We change that.

Who do we manage infrastructure for?

General SMEs (10-100 employees)

Limited or junior IT team, controlled budget, 'we don't want to deal with it'.

→ End-to-end managed infrastructure, monitoring included, single point of contact.

Scale-ups / SaaS startups

Urgent scalability, risk of infra slowing growth, exploding costs.

→ Auto-scaling K3s architecture, CI/CD pipelines, proactive monitoring, cost optimization.

Post-incident company

Trauma after major outage or hack. Management demands professionalization.

→ Existing infrastructure audit, secure reconstruction, Wazuh monitoring, continuity plan.

Fiduciaries & law firms

Ultra-sensitive data, professional secrecy obligations, DPA/GDPR/FINMA compliance.

→ 100% Swiss infrastructure, end-to-end encryption, sovereign workspace (Nextcloud).

Companies with confidential AI needs

Want to use AI but can't send data to OpenAI/Microsoft.

→ On-premise LLM (Ollama), Open WebUI interface, RAG on documents, all hosted in Switzerland.

False good solutions

Manage infrastructure internally

Recruit 1-2 senior DevOps (120-180k CHF/yr). Ongoing training. Dependency on 1-2 key people.
Viable from 50+ employees with a real IT department.

Standard / shared hosting

No strategic advice, limited responsiveness, standardized solutions, no proactive 24/7 monitoring.
Suitable for a showcase site. Insufficient for business apps.

US Hyperscalers (AWS, Azure, GCP)

Massive vendor lock-in, complex and unpredictable billing, data outside Switzerland, rare and expensive skills.
Oversized and risky for 80% of Swiss SMEs.

Freelance consultants

No long-term follow-up, availability not guaranteed, no 24/7 monitoring, variable quality.
Useful occasionally, but not for critical infrastructure.

There's a better approach: a local partner, OpenStack and open source expert, who manages your infrastructure on Swiss cloud as if it were their own.

FAQ

Frequently asked questions

Infomaniak is a Swiss host with datacenters in Geneva and Zurich, ISO 27001 certified. Your data stays in Switzerland, DPA/GDPR compliant, out of reach of the Patriot Act. Their Public Cloud is based on OpenStack - an open standard, so zero vendor lock-in.
Absolutely. We're agnostic. We can optimize your existing infrastructure with any provider. If sovereignty is a concern, we can plan a progressive migration to Infomaniak.
OpenStack is the world's most widely used open source cloud platform, developed by NASA, CERN, Walmart, Infomaniak. It's the open source equivalent of AWS/Azure, with the same building blocks (compute, network, storage).
Simple infrastructure (1-5 servers): 3-4 weeks. Medium (5-20 servers): 5-8 weeks. Complex (20+ servers, K8s): 8-12 weeks. Always with zero downtime.
No. Infomaniak costs are billed directly by the provider. We apply no markup. Our revenue comes exclusively from our services.
Our 24/7 monitoring detects most issues before user impact. If an outage occurs, we intervene in under 30 minutes. You receive a detailed post-mortem.
OpenStack runs the clouds of NASA, CERN, Walmart. Nextcloud is used by the German government. Kubernetes orchestrates Google, Spotify, Airbnb's infrastructure. Open source is the industry standard.
Of course. All code (Terraform, Ansible) is delivered to you. You have root access to your servers. Monitoring dashboards are accessible 24/7. Everything is documented and reproducible.
We deploy AI models (ChatGPT-like) directly on your servers, in Switzerland. Your data never leaves your infrastructure. We can connect the AI to your documents via a RAG system.
Three reasons: sovereignty (your data leaves the US), savings (no per-user license), freedom (no vendor lock-in). We handle configuration and maintenance.
Both. Audit, migration, AI deployment: project-based billing. Managed services, monitoring: monthly subscription. You can start with a project and switch to managed services later.
One-time projects: no long-term commitment. Managed services: 6 to 12 months. We favor long-term relationships based on results.
