What does 'Self Healing' refer to in cloud-native practices?

• A. Architecting your application to automatically resolve issues and restart processes when they fail.
• B. Manual intervention is required to restart crashed services.
• C. Self Healing means scaling resources preemptively before issues occur.
• D. Monitoring only, with no automated remediation.

Answer: (A)

Self-healing in cloud-native practices means the system automatically detects failures and recovers without human intervention. In Kubernetes, this is achieved by the control plane and health checks that ensure the desired state: unhealthy containers are restarted, failed pods are replaced, and workloads are rescheduled to healthy nodes until normal operation is restored. This automatic remediation is what the option describes when it says to design and run applications so issues are resolved and processes restarted on failure. The other ideas describe manual intervention, proactive scaling before issues occur, or monitoring without any automated fix, none of which embody self-healing.
