Alerts/Alarm

Get notification from monitor system

Run Book

Check

Check status of application/system

Restart service

If service is unhealthy, try to restart service Create a incident ticket to JIRA

Reboot instance

If service is still going unhealthy after restart, try to make snapshot for inspection

And reboot instance

Terminate instance

Finally, terminate instance to bring new one automatically
