i think there are other threads on this (or at least similar) topics.

i have multiple live apps on GAE:

www.starmakerstudios.com (plus iOS backend services)
www.diginn.com
www.elizabethscanvas.org

they all have *very* different usage profiles and costs.

given that i have spend 0 hours doing sysadmin on production GAE servers in 
years it has been worth it to me.  my largest app probably would need at 
least a half time sysadmin to keep running smoothly.  though i did get bit 
by google's pricing model change last year and it took lots of developer 
hours to adjust to the new pricing....but we have cleaner much more 
efficient code as a result.

instances run from 1 to as much as 40 depending on which app/traffic.  my 
highest usage app gets 30-50 requests per second on average.

i use datastore cause cloud SQL didn't exist when i started.  i suspect 
datastore is cheaper, though i don't know.

it depends on your app type for hosting on GAE.  don't do stats processing 
on GAE - the request limitations are horrible to deal with.  if you serve 
lots of short requests that display small/medium amounts of data, or update 
individual bits of data at a time it seems to be pretty good.  think 
through the types of request you want to do, and the costs of sysadmin vs 
working in the GAE way.  that should give your a way to frame your debate.

feel free to ask more questions....
