A rollback in DevOps refers to the process of reverting to a previous version of software that was previously known to work correctly. This is a critical procedure used to maintain software stability and performance in the event that a new deployment introduces bugs or undesired behaviors. Rollbacks are essential for establishing a reliable deployment process, as they allow teams to quickly revert to a stable state without significant downtime.

In practice, if a recent deployment introduces issues that could affect end users negatively, rather than spending time diagnosing and addressing the problems right away, a rollback can be initiated to return to the last stable version. This helps ensure that users have continuous access to functional software while developers fix the issues in the problematic release.

This process is a vital part of deployment strategies in DevOps, where rapid iterations and continuous delivery are prevalent. It underscores the importance of versioning and maintaining a history of builds to facilitate such reversions when necessary.
