In the era of in-house, internal-facing databases, manual monitoring and oversight were possible with minimal errors. The “how” of event reporting could take the form of emails, chat messages, webhooks, or custom application programming interfaces (APIs). And errors become especially worrisome as IT environments expand.

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.
