How Terraform’s simple graph concepts deploy complex infrastructure as code
summary
Claims that Terraform uses graph theory to order and execute resources, then shows it: a source‑code tour of Terraform core (Go), running init/plan/apply to create a random pet resource and inspect state, and tracing the code paths. The demo inspects the graph builder, the module expansion transformer (noting Terraform 0.13 changed module instances), the transitive reduction step, and the graph walk that executes nodes. The build runs and the plan/apply sequence produces the expected resource.
