Infrastructure as Code with Terraform
Manage AWS infrastructure through code with Terraform for consistent, repeatable deployments.
Terraform workflow from code to deployed infrastructure
Infrastructure as Code (IaC) transforms how we provision and manage cloud resources. Using Terraform, we define infrastructure in declarative configuration files that can be version controlled, reviewed, and applied consistently across environments.
Our Terraform workflow includes:
- Remote State - S3 backend with DynamoDB locking for team collaboration
- Modular Design - Reusable modules for common patterns (VPCs, ECS clusters, RDS)
- Environment Separation - Workspaces or directory structure for dev/staging/prod
- CI/CD Integration - Automated plan and apply through Jenkins or GitHub Actions
Key Concepts
- Version-controlled infrastructure changes
- Plan before apply - preview all changes
- State locking prevents concurrent modifications
- Drift detection identifies manual changes
- Import existing resources into Terraform management
