With the arrival of GAE 1.9.0 we do not need a payed application to use cloudstorage. I used to serve images using Google High Performance Image Serving using the blobstore and a get_serving_url.
Example:
Now I can serve images and other objects using cloudstorage and a default bucket:
http://storage.googleapis.com/<app_id>.appspot.com/<folder>/<filename>
Example:
https://storage.googleapis.com/jinjacms.appspot.com/energiekantoor/ek_sign.gif
What is the preferred method (cost / performance) besides other cloud storage benefits like folders, acl and metadata and if I do not need the size and crop arguments of get_serving_url.
Cloud Storage is way cheaper than a BlobStore. This is the only reason to move from BlobStore to Cloud Storage.
UPDATE (June 2014):
Google reduced the prices for both services. Now they cost the same.
