Terraform Development Services — Infrastructure as Code Across AWS, Azure & GCP

Terraform engineering — module design, state strategy, multi-account governance, policy-as-code, drift detection, and CI-driven plan / apply for multi-cloud estates.

What we build with Terraform

  • Module design with proper input / output contracts, semantic versioning, and reusable primitives
  • Remote state with S3 + DynamoDB locking, Terraform Cloud / HCP, or Spacelift
  • CI-driven plan / apply with policy gates (OPA / Conftest, Sentinel)
  • Multi-account / multi-subscription deployment patterns with workspaces or root modules
  • Drift detection and remediation workflows
  • Provider development for internal APIs and lesser-known services
  • Atlantis or GitHub Actions-driven self-hosted plan / apply
  • Migration paths between Terraform and CDK, Pulumi, or OpenTofu
  • Module testing with Terratest, Kitchen-Terraform, and policy unit tests
  • Cost estimation in CI with Infracost — guardrails before merge
  • Resource import for bringing console-deployed resources under IaC
  • Refactoring sprawling Terraform monoliths into versioned module catalogs
  • Compliance-aligned modules: SOC 2, HIPAA, PCI baselines as reusable Terraform code
  • Hybrid Terraform + Helm + Argo CD patterns for K8s + cloud infrastructure

Why DiveScale

Built by engineers who ship Terraform in production

Terraform is the multi-cloud IaC default — and the place where lots of teams accidentally ship spaghetti. DiveScale designs Terraform estates with clear module boundaries, versioned modules, and a state strategy that does not create surprise blast radius.

We default to CI-driven plan / apply through tools like Terraform Cloud, Spacelift, Atlantis, or GitHub Actions with proper approvals. Nothing applies from a laptop on production accounts. Plan output is reviewed; policy gates run; humans approve.

Module design is where Terraform investments compound or collapse. We design modules with clear input / output contracts, semantic versioning, and reusable primitives — so application teams consume modules by version rather than copy-paste their way to drift. The module catalog becomes a real internal product.

Multi-account governance is part of every serious Terraform engagement. Baseline stacks — networking, IAM, logging, security baselines — deploy across many accounts via workspaces or root-module patterns, with auto-deploy on new accounts. We pair this with policy-as-code (Sentinel, Conftest / OPA) so dangerous changes never make it to apply.

And we plan for the long arc: Terraform versions move, providers evolve, OpenTofu is now a real alternative for teams concerned about licensing. We architect so a future migration (or version jump) is a chore — not a crisis.

We take over sprawling Terraform estates regularly. A 2–3 week audit, identify the highest-risk patterns (state monoliths, untyped variables, click-ops gaps), and propose a refactor plan that lands incrementally without freezing infrastructure work.

Terraform use cases we deliver

Greenfield IaC estates

New AWS / Azure / GCP estates with module-first Terraform, versioned modules, CI-driven apply, and policy-as-code from day one.

Terraform refactors

Bring sprawling Terraform repos under control — module extraction, state surgery, and a clean versioned module catalog.

Multi-cloud / multi-account

Patterns for deploying baseline infrastructure across many accounts or subscriptions without copy-paste — workspaces, root modules, or external orchestration.

Policy as code

OPA / Conftest or Sentinel policies gating Terraform plans — cost, security, naming, and compliance enforced before apply.

Drift remediation

Scheduled drift detection with alerting and a remediation workflow — not just an unused dashboard.

OpenTofu migrations

Move from Terraform 1.x to OpenTofu where licensing, community direction, or open-source policy calls for it.

Resource import projects

Bring console-deployed resources under IaC control via the import operation — without rebuild or downtime.

Custom provider development

Build internal Terraform providers for proprietary APIs and lesser-known services.

Compliance-aligned modules

Reusable Terraform modules that encode SOC 2, HIPAA, or PCI baselines — so application teams inherit compliance posture by default.

Cost guardrails in CI

Infracost integration so cost impact is visible at PR time, with budget thresholds that block dangerous changes.

Terraform → CDK / Pulumi migration

When typed IaC becomes the right choice, we migrate Terraform estates to CDK or Pulumi without rebuild.

How we deliver

Our Terraform delivery process

  1. 01

    Estate audit

    Map current Terraform: modules, state files, providers, click-ops gaps, and the highest-risk patterns. Without this, refactors guess.

  2. 02

    Module catalog

    Versioned modules with clear contracts; consumer code calls them by version, not by Git ref.

  3. 03

    State strategy

    Remote state with locking, one state per logical workload, no monolithic root, and a clear path for state surgery when refactoring.

  4. 04

    CI/CD plan / apply

    Pipeline-driven plan / apply with approvals, policy gates, cost estimation, and drift detection on schedule.

  5. 05

    Multi-account rollout

    Baseline stacks deployed across accounts via workspaces, root modules, or orchestration. Auto-deploy on new accounts.

  6. 06

    Operate & evolve

    Terraform / provider upgrades, module catalog evolution, and routine state hygiene.

Terraform: Frequently Asked Questions

Terraform when multi-cloud or HCL fluency dominates, or when the ecosystem (modules, providers) matters most. CDK when AWS-only and typed languages are preferred. Pulumi when typed multi-cloud is the priority. We work in all three and pick honestly.
