Alon, Today, if I look at the Instances graph, the number of Total Instances is much higher than the Active Instances (and always has been) - in our case at the moment: 600 Total to about 150 Active.
Question: is the sample billing based on the Total Instances? I.e., is tuning down the Max Idle Instances a really easy cost savings? P.S., here are the shocking numbers we're facing: app1: 3.8x increase (5.3x increase when Python instances go up in price, unless we can get to 2.7 and thread-safety in time) app2: 17.8x increase (34x increase when Python instances go up in price, unless we can get to 2.7 and thread-safety in time) In terms of real $$, for app1, we are looking at going from around $60,000 / year to around $318,000 / year - that is a LOT of moola for an application. If we cannot optimize down, it will be a prohibitive amount of moola. j On Aug 31, 3:47 pm, "Alon (Google)" <[email protected]> wrote: > Hi All, > > If your large bill increase is attributable primarily to Frontend > Instance Hours, one of your best bets is to go to your 'Application > Settings' page and reduce the value for Max Idle Instances (don't > forget to click 'Save Settings').
