⏚ Summary

What this engagement is, plainly.

IaC is easy to start and hard to do well. We design IaC programs where the code accurately reflects the running system, drift is caught early, and 'click-ops' becomes the exception.

Problems we solve

  • You have Terraform but half your cloud is still managed by hand.

  • State files are in the wrong places, modules are duplicated, and 'terraform apply' makes people nervous.

  • Drift between code and reality keeps biting in incident retros.

⏚ Approach

How we run this engagement.

  1. 01Phase

    State discipline

    State storage, locking, and access controls done properly. State splits planned, not accidental. Drift detection automated.

  2. 02Phase

    Module architecture

    Composable modules with versioned interfaces. New environments are config, not copy-paste.

  3. 03Phase

    Policy + safety

    Plan output reviewed by humans for high-blast-radius changes; OPA / Sentinel policies for the rest. Apply is boring, on purpose.

⏚ Deliverables

What you get, signed off.

  • IaC architecture + module library

  • State management + drift detection

  • Policy bundle (OPA / Sentinel)

  • Workspace / environment hierarchy

  • Onboarding + safety runbooks

⏚ Stack we typically use

Tools, not religion.

We pick on workload and team shape, not on fashion. Anything below is a default — swappable when your context demands.

  • Terraform
  • Pulumi
  • Crossplane
  • Atlantis
  • OPA
  • Terragrunt

Outcome

An IaC program where the code is the truth, drift is detected automatically, and 'apply' is a routine action — not a high-stakes event.

Have a hard problem worth doing once, well?

We take a small number of engagements per quarter. If your program needs serious operators, we'd like to hear about it.
