If someone loads up a page that leaves them connected as a seat
on your database, and they type a word into a formfield, and
they go on vacation for 3 weeks, is that an "instance"? (
I meant "is that a 3-week-long instance" ... which could get pretty
darn expensive if you ever have a db admin who forgets to set the
pref for "disconnect guest when idle for __ minutes" and then even
though no EC2 resources are being consumed whatsoever, Amazon will
still charge you by the hour for that seat. I really don't get
charging for server space by "time" rather than by actual resources
consumed.
