Currently, with my launch, we are using the Blobstore service, and we plan to move to GCS. The only "drawback" I see is that you can no longer resize and crop images directly from the path ( Transforming_Images_from_the_Blobstore ).
In order not to slow down the entire client code, we are thinking of an internal servlet that changes on the fly with the CDN before, in order to cache the most recent jobs.
