The problem you're facing
Your infrastructure exists, but its description lives in administrators' heads and internal notes. Reproducing an environment, proving its configuration or understanding a change's impact: everything becomes an investigation. And an emergency restore, a nightmare.
Our answer
We describe your infrastructure as code: Terraform for resources, Ansible for configurations, all versioned in Git with review of every change. Reproducing an environment becomes one command; proving its configuration, a diff; and configuration errors, something read before they reach production.
What LaMeDuSe takes care of
- Infrastructure described in Terraform (cloud, network, machines)
- Configurations in Ansible (hardening, services, applications)
- Git versioning with review of every change
- On-demand reproducible environments
- Progressive migration plan from existing setup to IaC
- Deployment tests and validation
- Training your teams in IaC practice
Our methodology
- 1
Delivery chain diagnostic
Analysis of the path from commit to production: durations, manual steps, risks and bottlenecks.
- 2
Incremental automation
Quick wins first, then progressive industrialisation: tests, build, deployment, rollback.
- 3
Infrastructure as Code
All infrastructure versioned, reviewed and reproducible : no more untracked manual configuration.
- 4
Handover & autonomy
Documentation, training for your teams and knowledge transfer: you stay in control of your chain.
Relevant technologies
Security
Secrets managed outside the codebase (Vault, SOPS), dependency scanning, container image scans and signing of deployed artefacts.
Hosting & infrastructure
We run these practices on our own European infrastructure every day: what we deploy for you, we operate for ourselves.
Maintenance
Continuous improvement of the chain, version watch, and optional on-call support for your critical pipelines.
Why LaMeDuSe
Our own European infrastructure, datacenters, clusters, platforms, is managed as code by our teams. We don't teach a theory: we live the practice, with its pitfalls and real gains.
Frequently asked questions
No: migration happens through increments. Start with new environments, then progressively import the existing setup (Terraform import tools). The infrastructure keeps running during the rollout.
Both, because they don't do the same job: Terraform provisions (creates resources), Ansible configures (installs and tunes). The useful question is rather: which scope to automate first.
Three measurable gains: reproducibility (an environment recreates identically), traceability (every change is reviewed and versioned), and speed (what took a day of manual configuration takes minutes).
Done poorly, yes : which is why the approach matters: cleanly imported state, changes reviewed in pull requests, Terraform plans read before applying, and test environments. Done well, IaC reduces risk instead of increasing it.
