Just to emphasize what Kaan Soral said, without going into cheapness evaluation: "the initial costs seem to be high, but as the traffic increases, the costs doesn't increase proportionally. So basically, appengine gets cost efficient with increased traffic, seems logical - so basically you have to excuse the initial daily ~<10$ costs if you are keeping instances and memcached alive"
It goes way further than saving costs for keeping instances and memcache alive. When we launched one of our products, we had one engineer working on the back-end side (99% AppEngine). We had a few hundred daily active users. Then our product became very successful and we reached 5 million (!) daily active users. We still only had one engineer working on our back-end. @Tapir I'm sorry I can't really answer your 'Please share your GAE success stories!<http://groups.google.com/group/google-appengine/t/945c56ecd47682d4>' questions as I'm not allowed to share cost/revenue figures. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
