Terraform & OpenTofu map

The architect's blueprint. Draw the plan first, then build exactly that.

Every world is open. T1 to T3 build on each other. Lessons use OpenTofu. Terraform uses the same language.

Tip: best after Git & GitHub, World 4. Not a lock. Start any time.

Tip: best after CI/CD, World C1. Not a lock. Start any time.
