Our IaC practice treats infrastructure with the same engineering rigour as application code: peer review, automated testing, and CI/CD pipeline integration are non-negotiable. The result is a cloud environment that is predictable, self-documenting, and safe to change. [Home](https://claritasone.com/) › [Services](https://claritasone.com/services) › [Cloud Services](https://claritasone.com/services/cloud-services) › **Infrastructure As Code** ## Overview Configuration drift is one of the most insidious risks in enterprise cloud operations. When infrastructure is provisioned manually — through console clicks, ad-hoc scripts, or undocumented tribal knowledge — every environment slowly diverges from its documented state until no one in your organisation can state with confidence what is actually running in production. This drift creates the security vulnerabilities, outage root causes, and compliance failures that surface at the worst possible moments. Claritas IaC engagements address the technical debt of manual infrastructure by systematically codifying your environment into version-controlled Terraform or Pulumi modules — and equally importantly, by implementing the policy guardrails, automated testing, and CI/CD integration that prevent drift from accumulating again. The compliance dividend is substantial: auditors receive a complete, immutable history of every infrastructure change with associated approver identity and business justification. ## Our Approach ### 1. IaC Readiness Assessment & Strategy We assess your current infrastructure provisioning maturity, identify the highest-value targets for codification, and recommend an IaC toolchain and module strategy appropriate to your team topology and cloud footprint. A phased implementation roadmap is produced with effort estimates and business value projections for each phase. ### 2. Module Architecture & Repository Design We design a modular IaC architecture — separating foundational network and security modules from application-layer infrastructure — with a repository structure and naming convention that scales to hundreds of modules across multiple cloud accounts. Remote state management, workspace strategy, and module versioning policies are established before implementation begins. ### 3. Codification & Migration Existing infrastructure is imported into Terraform or Pulumi state — a high-risk activity that we execute with explicit rollback plans and change freeze windows. New infrastructure is provisioned exclusively through code from this point forward, with console access restricted to break-glass emergency procedures. ### 4. Policy as Code & Compliance Automation OPA Gatekeeper, Sentinel, or Checkov policies are implemented to enforce security and compliance standards automatically in the pipeline — preventing non-compliant infrastructure from being provisioned regardless of the engineer making the change. Policy violations block pipeline execution and produce human-readable remediation guidance. ### 5. CI/CD Integration & Drift Detection IaC changes flow through the same CI/CD pipeline governance as application code: automated plan generation, policy validation, peer review, and approval gating before apply. Drift detection runs on a scheduled basis and alerts your operations team to any out-of-band changes that threaten environment integrity. ## Capabilities - Terraform module development, state management, and workspace strategy at enterprise scale - Pulumi TypeScript/Python infrastructure development and stack management - AWS CDK and CloudFormation template design and stack management - Policy as Code: OPA/Conftest, Sentinel, and Checkov in CI pipeline gates - Automated drift detection and out-of-band change alerting - Multi-environment promotion workflows: dev, staging, production with approval gates - IaC testing: Terratest, pytest, and contract testing for infrastructure modules - Compliance audit trail: every change attributed, reviewed, and immutably logged ## Outcomes | Metric | Value | | --- | --- | | Infrastructure changes through version-controlled pipelines post-engagement | **100%** | | Configuration drift incidents when drift detection is active | **Zero** | | Target environment provisioning time vs. days manually | **15 min** | | Reduction in compliance audit preparation time | **90%** | ## Next Step **If your infrastructure cannot be reproduced from code, it cannot be trusted.** Commission our IaC practice to codify your cloud environment, eliminate configuration drift, and give your compliance team the immutable audit trail that regulators demand. → [Get a proposal](https://claritasone.com/get-a-proposal) · [Contact us](https://claritasone.com/contact) --- View the live page: About Claritas One: · Contact: · All pages:
