Comparison

Terraform Vs Manual Diagrams

Manual tools are great for brainstorming. Terraform-driven diagrams are better for staying current as infrastructure changes.

Terraform-driven

  • - Reflects real infrastructure code
  • - Faster updates after each change
  • - Better for ongoing architecture documentation
  • - Easier to review drift and dependency changes

Manual diagramming

  • - Flexible for workshops and early ideation
  • - High effort to keep updated
  • - Often drifts from deployed reality
  • - Harder to scale across many environments

Recommendation

Use manual diagrams for discovery sessions, then shift to Terraform-based generated diagrams as the system stabilizes. This keeps architecture communication accurate without repetitive manual rework.
