Infrastructure as Code with Terraform, OpenTofu and Ansible
ARTechOps turns manually built infrastructure into reviewed, version-controlled code using Terraform or OpenTofu for provisioning and Ansible for configuration. We add policy-as-code checks and drift detection so environments stay reproducible.
What We Deliver
- Modular Terraform and OpenTofu architecture
- Ansible configuration automation
- Policy-as-code validation
- Drift detection and state synchronisation
Typical Deliverables
- Reusable, documented IaC modules
- Remote state and environment structure
- CI checks for plan, lint and policy
Tools & Platforms
- Terraform
- OpenTofu
- Ansible
- Python
- Bash
- Linux
Frequently Asked Questions
Terraform or OpenTofu: which do you use?
Both are supported. We pick based on your licensing preference and existing state; the modules and workflow are largely the same.
Can you import our existing, manually created infrastructure?
Yes. We import resources into state and codify them in stages so production is not disrupted.
How do you prevent configuration drift?
All changes go through pull requests and pipelines, and scheduled plan runs flag any difference between code and the live environment.
