Platform architecture

Terraform-Safe OCI Platform Foundation

Turned OCI environment changes into a reviewed Terraform path with state checks, IAM guardrails, and release gates.

Role

Architecture + delivery

Stack

OCI / Terraform

Outcome

500+ resources protected

Problem

Infrastructure changes were risky when ownership, state impact, and promotion steps were unclear.

Action

Defined Terraform boundaries, IAM checks, promotion gates, and a release-review flow; separated state-sensitive resources into reviewable units before production execution.

Result

Protected 500+ OCI resources per environment and made changes easier to review, promote, and operate.

Evidence

Environment promotion diagram and release checklist covering state impact, IAM boundary, network blast radius, and rollback path.

key decisions

  • Treat Terraform state as a production asset, not an implementation detail.
  • Keep IAM, networking, and runtime boundaries visible during review.
  • Use environment promotion gates to reduce drift and surprise recreation.

Release checklist

A release checklist for Terraform-safe platform changes.

  • State impact reviewed
  • IAM boundary checked
  • Network blast radius understood
  • Rollback path documented

portable standard

The cloud primitives change by provider, but the standard is portable: state boundaries, least privilege, review gates, and controlled promotion.
