GitOps ensures infrastructure stays aligned with Git, eliminating ad-hoc fixes. Automated failover and rollback strategies with tools like ArgoCD and Argo Rollouts detect failures, revert incorrect updates, and restore the last working version, while Kubernetes health probes monitor application readiness. GitOps provides a more automated and controlled approach to rollbacks, especially when managing numerous microservices at scale, ensuring consistent rollbacks across all affected services, restoring the entire system to a known good state while preventing cascading failures.
