Strategy for large multi-team IaC projects
WHAT IT TESTS: scaling IaC organizationally. OUTLINE: versioned reusable modules, state split per environment and component, promotion of identical code via variables, and externalized secrets. RED FLAG: one giant shared state or secrets in code.
WHAT IT TESTS: whether you can structure IaC for many teams and environments safely. ANSWER OUTLINE: factor reusable modules with versioned interfaces; isolate state per environment and component to limit blast radius and locking; promote identical module code from dev to staging to prod via environment-specific variables, not divergent copies; pull secrets from a dedicated store at apply time, never committed; and gate changes through CI with plan review. RED FLAG: a single monolithic state or secrets in version control.
