Deployment, Environments & Rollback
These delivery practices move a tested version through separate environments. They also keep a safe way to return to an earlier state.
Another example
A release goes to staging and passes smoke tests. It moves into production bit by bit. A feature flag or revert stays ready.
Main parts
- 01Branch or change set
- 02Review and verification gate
- 03Released result
Use it when
Use fixed artifacts, settings per environment, health checks, and a practiced recovery plan.
Do not use it when
Never trust unclear manual steps or production-only changes. Every release needs a safe return path.

staging → canary → production → rollback Before you ship
Before publishing, check the exact repository, branch, target, and diff. Keep unpublished work. Pass review and CI checks. Record conflict and data-loss risks, release order, traceability, recovery, and rollback.
Outcome: Use Deployment, Environments & Rollback to release or recover the change safely, with a clear record. User context: A release goes to staging and passes smoke tests. It moves into production bit by bit. A feature flag or revert stays ready. Delivery concept or operation: Deployment, Environments & Rollback. Why it fits: Use fixed artifacts, settings per environment, health checks, and a practiced recovery plan. Do not use it when: Never trust unclear manual steps or production-only changes. Every release needs a safe return path. Delivery requirements: Name the code repository and target. List preconditions, changes, review and CI checks, conflict and data-loss risks, release order, and the rollback or recovery command. Repository safeguards: Keep unpublished work and a clear history. Do not run destructive steps without an explicit backup. Check the exact code diff and remote target before publishing. Acceptance criteria: Review the intended diff and pass all required checks. Keep the target version traceable. Practice failure recovery and keep published history clear. Evidence and limits (evidence boundary): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Repository, branch, team activity, release environment, approval owner, protected checks, and rollback target.
