Overview

Value: A project to automate the provisioning, configuration, and management of IT infrastructure using code, enabling repeatable, reliable, and scalable infrastructure deployments across cloud and on-premises environments. To standardize and automate infrastructure management, reduce manual errors, accelerate environment provisioning, and enable version-controlled infrastructure changes.

Problem: The IaC codebase is modular, supporting multiple cloud providers (AWS, Azure, GCP). All infrastructure code is peer-reviewed and subject to automated testing before deployment. The project follows best practices for idempotency, modularity, and version control. Regular audits are conducted to ensure compliance with security and operational standards.

Solution: To standardize and automate infrastructure management, reduce manual errors, accelerate environment provisioning, and enable version-controlled infrastructure changes.

Getting Started

To implement this use case, you need GitLab with CI/CD capabilities, Infrastructure as Code tools like Terraform or Ansible, and appropriate cloud or infrastructure access.

  1. Set up GitLab repository with IaC tools integration and CI/CD pipelines
  2. Define infrastructure code structure and modular organization
  3. Configure automated testing and validation pipelines
  4. Implement secrets management and secure credential handling
  5. Establish monitoring and drift detection procedures

FAQ

How does Infrastructure as Code improve reliability?

IaC provides version control, automated testing, and consistent deployments, reducing manual errors and enabling quick rollbacks when issues occur.

Can IaC work with existing manual infrastructure?

Yes, IaC can be gradually adopted by importing existing resources and incrementally managing them through code.

How are secrets and sensitive data managed?

Secrets are managed through secure vaults and encryption, never stored in plain text in repositories, with controlled access through CI/CD variables.
