terraform-infrastructure

Terraform automates multi-cloud infrastructure provisioning by defining resources declaratively in HCL, then planning and applying changes across AWS, Azure, GCP, and other providers. Write configuration files, run terraform plan to preview changes, and terraform apply to provision networks, compute, storage, databases, and Kubernetes clusters consistently.

Terraform state tracks your deployed infrastructure and enables remote collaboration. State files store resource mappings, support backend locking to prevent conflicts, and allow teams to apply changes safely through shared, versioned infrastructure definitions rather than manual configuration.

Yes. Terraform modules encapsulate reusable infrastructure components—networks, databases, Kubernetes clusters—that you parameterize for different environments. Define modules once, version them in version control, and apply them consistently across projects with environment-specific variables.

Use CI/CD workflows to run terraform plan and terraform apply automatically on code changes. This enforces plan-before-apply validation, enables GitOps practices, prevents manual drift, and creates an audit trail of all infrastructure changes tied to version control commits.

Terraform's declarative model and state management detect drift—when actual resources diverge from configuration. Running terraform plan reveals differences; terraform apply realigns infrastructure to match code, ensuring immutable, consistent, and auditable infrastructure across all cloud providers.

Structure modules by component (networking, compute, databases) and parameterize them for region and environment. Use remote state backends with disaster-recovery support, configure cross-region resources, and version modules in version control to enable repeatable, recoverable infrastructure deployments.
