Ok for the past 1h40 my app have been running with 4 resident instances and ~3 dynamic instances.
I have found only 9 warmup requests and no user-facing loading requests. Great ! But among the 4 resident instances 3 served only 1 request and the last one only 75 (cf. below). <https://lh5.googleusercontent.com/-1_KBMpk_0n0/UPnbxhMtZpI/AAAAAAAA0BU/n3YvDAXXU7I/s1600/Instances+-+VinoCities+-+Google+Chrome_2.jpg> <https://lh5.googleusercontent.com/-EivCzKUJMq4/UPncw4uUhtI/AAAAAAAA0Bg/FiPCMktQMYY/s1600/Dashboard+-+VinoCities+-+Google+Chrome.png> Minimal price for such a configuration : 0.05 (reserved hour) * 7 (instances) * 24 (hours) * 30 (days) = $256 / month. Isn't it a bit expensive for such a low traffic website ? In my personal case I can't afford it. Google, can you confirm that we need such a configuration to avoid user-facing loading requests for GAE Java apps ? Thanx for your answer. PS: On my point of view, there is definitely something broken in the scheduler, such a waste of resources and energy is not ecological at all. If GAE is only suited for very high traffic Java apps, it should be clearly stated somewhere in the docs then. Could we imagine using a different scheduler for low traffic apps ?
