Rollback
Domain: MLOps
🎯 Motivation
Reverting to a previous model version when the new version has problems. Quick recovery from bad deployments.
📋 Concrete Example
New model v3 deployed. Error rate jumps from 0.1% to 5%. Rollback to v2 immediately. Users are unaffected. v3 is fixed and redeployed later.
🔗 Analogy
Ctrl+Z in a word processor - you made a change that broke everything. Undo (rollback) to the previous version. Quick recovery.
