What process would you use to revert changes after a deployment that caused issues?

The concept of rollback is crucial in deployment scenarios where changes need to be reversed due to unforeseen issues or failures. When a deployment has introduced problems, a rollback is specifically designed to revert the system back to a previous stable state. This process allows developers and system administrators to undo the changes made during the last deployment, effectively restoring the application or service to its earlier functioning condition without losing significant functionality or data integrity.

Rollback mechanisms are often implemented through version control systems or deployment tools that manage application states, allowing for quick recovery from deployment-related defects. This ability to quickly revert to a known good state minimizes downtime and disruption for end users.

In contrast, the other options represent different processes that don’t align as closely with the need to specifically undo changes from a recent deployment. Restore might imply recovering data from backup, which is a more situational process that doesn't necessarily deal directly with application deployment. Redeploy suggests launching the application again, potentially with the same problematic changes intact, while halt simply stops current operations but does not address reverting to a functional state. Rollback is the most appropriate term for this specific scenario involving the reversion of changes post-deployment.
