I am little confused about outoging traffic cost in GAE projects.
see: https://developers.google.com/storage/docs/pricingandterms
So, if u use GAE outgoing traffic costs $0.12 always. However if google cloud storage service is used, u get higher cost ($0.21) when sending data to Asia. Why is that?
So this basically mean, if i send 100GB of data to Asia via my GAE app, it will cost me $12, but if i publish my data in public cloud storage buckets, same 100GB transfered would cost $21. Or am i wrong here?
You are correct.
To save monthly costs (not development costs), you can serve your content from your GAE instance. You can essentially have a relay functionality in your GAE to serve content from your cloud storage. Is it worth the $0.10/GB, only you’ll know based on your traffic demands.
