Terraform debt cleanup
Infrastructure changes were risky, state locks were common, and nobody trusted what plan would do. The team needed IaC that was safe, readable, and predictable.
- Frequent state locks and unexplained diffs
- Manual console changes to keep systems alive
- Modules too coupled to refactor safely
- Drift and environment confusion
IaC became a source of risk
Environment
Multi-environment SaaS platform with a patchwork of Terraform modules.
Trigger
Unsafe applies and drift blocked delivery and created risk.
Constraints
No appetite for big-bang refactors.
Goal
Create safe change control without stopping delivery.
Make Terraform boring again
State stabilization
Protected state, resolved lock patterns, and mapped ownership.
Module cleanup
Reduced coupling and clarified environment boundaries.
Drift reduction
Removed manual patches and rebuilt repeatable change paths.
Guardrails
Review flows, validation, and safer apply sequences.
Controlled changes and restored confidence
Safe applies
Changes were predictable and repeatable.
Lower risk
Drift and unknown diffs stopped compounding.
Audit readiness
Clear ownership and evidence of change control.
Reusable assets for the team
Module map
Ownership boundaries and dependency clarity.
Change runbook
Standard operating procedures for applies.
Drift report
Baseline of known gaps and remediation plan.
