This lesson focuses on CI/CD Promotion, Plan Integrity, Drift, and GCP Operations and its role in the wider engineering advanced Google Cloud infrastructure with Terraform, reusable modules, organization controls, secure state, CI/CD promotion, policy checks, and operational validation workflow.
Learners work with the actual design choices, dependencies, controls, and failure modes that distinguish this topic from a generic Terraform exercise.
Promote a reviewed GCP plan through a protected pipeline.
Detect and remediate an out-of-band firewall change through code and evidence.
The applied change matches the reviewed plan and post-deployment checks confirm the intended result.
Handle stale plans, expired tokens, concurrent changes, eventual consistency, 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.
