Take the 2-minute tour ×  I'm the sole user of a my google app
engine app. Currently I use approx 25% of my front end instance
hours per day. Does this seem excessive ? Reason I'm asking is
that if I begin to allow other user to use my app I will quickly
exceed the daily quota ?  So if I add 3 more users that use
exactly the same functionality I will use 100% of my front end
instance hours. Is it this simple to calculate the cost of
allowing multiple users to use my app ? If not how can I
estimate the frontend Instance hours when app becomes mult-user
based on current usage for one user?  share|improve this
question  1 Answer 1  up vote 1 down vote accepted  You get
enough front end hours to run your application 24/7. Even if you
add 3 more users you'll still only be at 100% which is fine. You
can't use "more" then 100% with a single instance plus you in
fact get 28 instance hours a day free, not 24.  If you were to
allow more instances to spin up then of course you can go over
100% (i.e. over the free quota)
