I run several containers on my server, many of which need postgres, mysql, etc, as a database. So far, I have just given them all their own instance of database. Lately I've been wondering if I should just have one separate single database server that they each can share.

I'd imagine that the pro of this somewhat reduced resources and efficiency. The cons would be that it would be a little harder to set up, and a little more complexity in networking and management, and it maybe more vulnerable that all the applications would go down if this database goes down.

I am setting up a new server and so I want to see other's take on this before I make a decision on what to do.
