Who was responsible for support, and how were issues with the product handled?

Support teams or DevOps engineers, and sometimes developers, usually participate in supporting production systems. Issues with production come from various sources:

• Monitoring and alerts — monitoring systems (Prometheus, Zabbix, Grafana) automatically notify about failures.
• User reports — bugs or errors affecting users can be recorded through tickets or chat.
• Logs and traces — log analysis helps identify the causes of problems.

It is important to respond quickly, reproduce the problem, analyze the root cause, and fix it. An incident management system (e.g., PagerDuty) is often used.

Communication with the development team is also crucial for quick releases of fixes and preventing recurring incidents.
