Infrastructure as a Code Best Practices with Terraform
summary
Terraform code organizes into reusable modules (example: VPC landing‑zone module that creates multiple subnets and scales by input variables), stores state remotely (S3 for state with DynamoDB for locking and versioning), and enforces secrets handling (no hardcoded API keys — use AWS Secrets Manager, Parameter Store, or HashiCorp Vault). CI/CD integration appears as GitLab/Jenkins/CodePipeline running automated terraform plan/apply and drift checks. The concrete workflow shown deploys an AWS VPC landing zone by changing inputs — the setup is repeatable and the remote state plus locking prevents common conflicts.
