Infrastructure as Code (IaC)

Build infrastructure that is repeatable, consistent, and easy to change.

Infrastructure as Code replaces manual configuration with version-controlled, automated infrastructure definitions. This reduces configuration errors and drift, makes changes traceable and reviewable, and enables environments to be reproduced reliably - from development and testing to production.

Overview

Manual infrastructure changes are difficult to reproduce, audit, and maintain consistently. I help organisations introduce or improve Infrastructure as Code (IaC) practices to manage servers, networks, cloud resources, and system configuration through version-controlled code.

What I Can Help With

  • Infrastructure Automation - Replace repetitive manual provisioning and configuration tasks with automated, reproducible workflows.
  • Configuration Management - Define and maintain consistent system configurations using tools such as Ansible.
  • Infrastructure Provisioning - Create and manage infrastructure declaratively using tools such as OpenTofu or Terraform.
  • DNS as Code - Manage DNS zones and records through version-controlled configuration and automated deployment.
  • CI/CD Integration - Validate, review, test, and deploy infrastructure changes through automated pipelines.
  • Existing Infrastructure Migration - Gradually bring manually managed infrastructure under Infrastructure as Code without requiring a complete rebuild.

Typical Outcomes

  • Reproducible and consistent infrastructure
  • Fewer errors caused by manual configuration
  • Infrastructure changes tracked through version control
  • Peer-reviewable and auditable changes
  • Faster provisioning and recovery
  • Reduced configuration drift
  • Easier maintenance and knowledge transfer

How I Work

I start by reviewing your existing infrastructure, operational processes, and automation requirements. Together, we identify suitable areas for Infrastructure as Code and choose an approach appropriate to your environment.

Implementation can be introduced incrementally, starting with high-value or frequently repeated tasks rather than attempting to automate everything at once. Infrastructure definitions are kept in version control and can be integrated with testing, review, and deployment workflows.

Deliverables

Depending on the engagement, deliverables may include:

  • Infrastructure as Code repository and configuration
  • Ansible roles and playbooks
  • OpenTofu or Terraform modules and configurations
  • Automated validation and deployment workflows
  • Migration of existing infrastructure to managed configuration
  • Documentation and operating procedures
  • Knowledge transfer and training

Technologies & Standards

Typical technologies include Ansible, OpenTofu, Terraform, Git, CI/CD pipelines, and octoDNS. The specific toolset depends on your existing infrastructure and requirements.

Discuss Your Requirements

Every infrastructure environment is different. Whether you want to introduce Infrastructure as Code, improve an existing setup, or automate a specific part of your infrastructure, I can help you identify a practical approach.
