Hello Jörg, The flexible environment does allow you to write to a directory on a local disk, but written files are ephemeral, due to the fact that the disk gets initialized on each VM startup, so your files will get deleted on this occasion. You can read more related detail on the "Choosing an App Engine Environment" online documentation page <https://cloud.google.com/appengine/docs/the-appengine-environments>.
You can profit from the facilities offered by the Compute Engine, if writing to disc is a must. By default, each Compute Engine instance has a single root persistent disk that contains the operating system, as stated on the "Storage Options" page <https://cloud.google.com/compute/docs/disks/>. For more insight, you may implement the proposed example <https://cloud.google.com/php/tutorials/bookshelf-on-compute-engine> from the "Running the PHP Bookshelf on Compute Engine" page. The Compute Engine does not handle scaling up of your applications automatically, so you'll have to take care of it yourself, as suggested in the "Autoscaling Groups of Instances" document <https://cloud.google.com/compute/docs/autoscaler/>. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
