This lesson focuses on State, Collaboration, Drift, and Safe Change and its role in the wider building a platform-engineering foundation with Terraform workflows, resource graphs, variables, state, modules, testing, collaboration, and infrastructure standards workflow.
Learners work with the actual design choices, dependencies, controls, and failure modes that distinguish this topic from a generic Terraform exercise.
Move local state to a collaborative backend and reconcile an out-of-band change.
Design a state boundary for shared network and application infrastructure.
State ownership is clear and the plan contains no unexplained destructive action.
Recover from stale locks, backend changes, incorrect imports, and drift.
Learners isolate the smallest verified cause, correct it, rerun the relevant validation step, and record the preventive action in the course improvement log.
