Google releases App Engine billing plan Preview

In addition to the free resources currently provided by gae, users can purchase computing power as needed. with regard to this function, the Gae team released some updates and released an interface.

Like adwords, users can set the daily budget. The budget indicates the highest price you are willing to pay every day. If the actual usage is less than your budget, fees are charged based on the actual usage. at the same time, users can allocate their own budgets in different resources. You can specify a daily maximum budget of 2 US dollars, of which 25% is used for CPU time, that is, 50 cents, the bandwidth and storage are 25% different. this is better, so that users can use different plans for different types of applications (large background CPU computing, large data volume or large traffic. this better meets the on-demand computing objectives of the App Engine.
I don't know if the traffic of memcache, datastore and mail is not counted in the bandwidth quota. I remember that communication between Amazon EC2 and other services (such as S3) is not counted in traffic.

The latest price information is also displayed:
* $0.10/CPU core hour

It is similar to the original estimated price. The original estimated price:
* $0.10-$0.12/CPU core hour
* $0.15-$0.18/GB space per month
* $0.11-$0.13/output bandwidth per GB
