Share your experience in supporting and maintaining a specific service or system.

In my experience supporting and maintaining services, key tasks included:

• Monitoring service status using systems (Prometheus, Grafana, Zabbix).
• Incident handling: quick response to alerts, log analysis, troubleshooting.
• Updating and deploying new versions with minimal downtime using CI/CD pipelines.
• Performance optimization and scaling as load increases.
• Documenting processes and automating routine tasks.

For example, when supporting a web service, I set up automatic availability checks, analyzed logs to identify bottlenecks, and implemented scripts for automatic recovery in case of failure. This helped reduce downtime and improve stability.
