Self-healing systems are technologies designed to automatically detect and recover from faults or failures without human intervention. These systems use algorithms and sensors to monitor their performance, identify issues, and implement corrective actions, ensuring continuous operation and minimal downtime. Commonly found in areas like computer networks, software applications, and cloud computing, self-healing systems enhance reliability and efficiency. By proactively addressing problems, they reduce the need for manual troubleshooting and maintenance, ultimately leading to improved user experiences and lower operational costs.
