Rollback is the process of reverting a system to a previous state, typically used when a deployment or change causes issues. Rollbacks are a critical component of release management and disaster recovery strategies, providing a safety net when new code or configurations introduce problems. By reverting to a known good state, rollbacks help restore system functionality and minimize downtime. Automated rollback mechanisms can be integrated into CI/CD pipelines to quickly respond to deployment failures, ensuring stability and continuity in production environments.
