Database Administration is a tough, often ungrateful job. Especially if you run a 24/7 business-critical MySQL or MariaDB deployment.
MySQL has proven to be a remarkably solid database which supports billions of dollars in revenue. On some level this very solidity creates a false sense of security. There are many things that can wrong at any given time, whether that is a change to your app, a bug in the database, hardware failure or just simply running out of disk space.
Percona recently conducted a poll: “What keeps you up at night?”
Not surprisingly, "Downtime/HA" is very high on the list.
While there are many challenging issues and tasks that a DBA must deal with day-in and day-out, the one thing that always gets the Management team’s attention is Service Down, along with the loss of the revenue caused by the outage.
DBA's should ask two questions: "How much do you value your own sleep?" and "How much revenue does your company lose if the service is down for 30 minutes?"
While the first one may be personally more important for the DBA, the real question is the latter. Often the downtime is even longer than 30 minutes, which leads to a large, immediate revenue loss combined with longer-term revenue losses when your customers depart due to frustration. Such situations tend to put a DBA's job at risk.
