Industry Industrial SME — Geneva 3 months

Migrating an SME to Infomaniak Public Cloud

Moving an ageing on-premise infrastructure to Infomaniak Public Cloud (OpenStack), with fully declarative infrastructure and a validated disaster recovery plan.

Context

A Geneva-based industrial SME was running its ERP, file shares and internal tools on three physical servers hosted in its premises. End-of-life hardware, manual backups, no tested recovery plan.

The goal: get out of the local datacentre without losing data sovereignty (Swiss hosting required), while laying the foundation for modern infrastructure management.

Work delivered

Full audit of the existing setup (load, dependencies, maintenance windows)
Choice of Infomaniak Public Cloud (OpenStack) for Swiss sovereignty
Target design: VPC, subnets, security groups, load balancers
Terraform code for the entire infrastructure (reusable modules)
Ansible provisioning of the VMs (hardening, monitoring, backups)
Migration in batches with planned windows (4 weekends)
Disaster recovery plan tested for real: full restore in under 2 hours

Outcome

100% of the infrastructure described as code, versioned in GitLab
Infrastructure costs reduced by ~35% (vs. hardware amortisation + maintenance)
Encrypted, automated, weekly-verified backups
Internal team trained on Terraform and OpenStack basics (2-day training)
