What is an on call DevOps?

On Call DevOps are IT professionals who are responsible for maintaining the reliability, availability, and performance of software systems, especially outside regular business hours. They are 'on call' to respond to incidents, outages, or urgent issues that may arise in production environments. Their role is crucial for minimizing downtime, quickly resolving problems, and ensuring that services run smoothly 24/7. On Call DevOps often work with monitoring tools, automated alerts, and incident response protocols to efficiently address problems as they occur.
