Not everything can be addressed on the database side. Unrestricted connection settings: Leaving connection settings, such as max_connections and per-user limits, wide open exposes the system to malicious Denial-of-Service (DoS) attacks. App-Dev often demands unrestricted, uncontrolled access to the database.

Data redundancy, a database version of a RAID Pondering the case of high availability and redundancy, one replicates data by creating a replica via streaming replication.

Why not just create another database on the same instance? We split databases by function/team to give each team full autonomy over their schema, And if someone screws up, it breaks their cluster, not all databases. So you put multiple MySQL servers on a single machine instead of multiple databases inside one MySQL instance.

Over the years of being a DBA, I had to deal with all kinds of problems in the database.
