Terraform Patterns for Multi-Cloud Enterprise Infrastructure

Terraform enables consistent infrastructure across clouds, but enterprise scale requires discipline.

Module Design

• Keep modules focused and single-purpose
• Version modules independently
• Use private registries for organizational modules
• Document inputs, outputs, and examples

State Management

Remote state is non-negotiable. Use workspace separation for environments. Consider state locking and encryption.

Multi-Cloud Considerations

Abstract common patterns into modules. Accept that some resources are cloud-specific. Plan for provider version constraints.

Team Workflows

• Feature branches for infrastructure changes
• Terraform plan in PRs
• Apply only from CI/CD
• Drift detection scheduled runs
